|
||
character encoding in a streaming (incremental) manner.</p>
|
||
<p>The various <code>encode_*</code> methods take an input buffer (<code>src</code>) and an output
|
||
buffer <code>dst</code> both of which are caller-allocated. There are variants for
|
||
both UTF-8 and UTF-16 input buffers.</p>
|
||
<p>An <code>encode_*</code> method encode characters from <code>src</code> into bytes characters
|
||
stored into <code>dst</code> until one of the following three things happens:</p>
|
||
<ol>
|
||
<li>
|
||
<p>An unmappable character is encountered (<code>*_without_replacement</code> variants
|
||
only).</p>
|
||
</li>
|
||
<li>
|
||
<p>The output buffer has been filled so near capacity that the decoder
|
||
cannot be sure that processing an additional character of input wouldn't
|
||
cause so much output that the output buffer would overflow.</p>
|
||
</li>
|
||
<li>
|
||
<p>All the input characters have been processed.</p>
|
||
</li>
|
||
</ol>
|
||
<p>The <code>encode_*</code> method then returns tuple of a status indicating which one
|
||
of the three reasons to return happened, how many input code units (<code>u8</code>
|
||
when encoding from UTF-8 and <code>u16</code> when encoding from UTF-16) were read,
|
||
how many output bytes were written (except when encoding into <code>Vec<u8></code>,
|
||
whose length change indicates this), and in the case of the variants that
|
||
perform replacement, a boolean indicating whether an unmappable
|
||
character was replaced with a numeric character reference during the call.</p>
|
||
<p>The number of bytes "written" is what's logically written. Garbage may be
|
||
written in the output buffer beyond the point logically written to.</p>
|
||
<p>In the case of the methods whose name ends with
|
||
<code>*_without_replacement</code>, the status is an <a href="enum.EncoderResult.html"><code>EncoderResult</code></a> enumeration
|
||
(possibilities <code>Unmappable</code>, <code>OutputFull</code> and <code>InputEmpty</code> corresponding to
|
||
the three cases listed above).</p>
|
||
<p>In the case of methods whose name does not end with
|
||
<code>*_without_replacement</code>, unmappable characters are automatically replaced
|
||
with the corresponding numeric character references and unmappable
|
||
characters do not cause the methods to return early.</p>
|
||
<p>When encoding from UTF-8 without replacement, the methods are guaranteed
|
||
not to return indicating that more output space is needed if the length
|
||
of the output buffer is at least the length returned by
|
||
<a href="#method.max_buffer_length_from_utf8_without_replacement"><code>max_buffer_length_from_utf8_without_replacement()</code></a>. When encoding from
|
||
UTF-8 with replacement, the length of the output buffer that guarantees the
|
||
methods not to return indicating that more output space is needed in the
|
||
absence of unmappable characters is given by
|
||
<a href="#method.max_buffer_length_from_utf8_if_no_unmappables"><code>max_buffer_length_from_utf8_if_no_unmappables()</code></a>. When encoding from
|
||
UTF-16 without replacement, the methods are guaranteed not to return
|
||
indicating that more output space is needed if the length of the output
|
||
buffer is at least the length returned by
|
||
<a href="#method.max_buffer_length_from_utf16_without_replacement"><code>max_buffer_length_from_utf16_without_replacement()</code></a>. When encoding
|
||
from UTF-16 with replacement, the the length of the output buffer that
|
||
guarantees the methods not to return indicating that more output space is
|
||
needed in the absence of unmappable characters is given by
|
||
<a href="#method.max_buffer_length_from_utf16_if_no_unmappables"><code>max_buffer_length_from_utf16_if_no_unmappables()</code></a>.
|
||
When encoding with replacement, applications are not expected to size the
|
||
buffer for the worst case ahead of time but to resize the buffer if there
|
||
are unmappable characters. This is why max length queries are only available
|
||
for the case where there are no unmappable characters.</p>
|
||
<p>When encoding from UTF-8, each <code>src</code> buffer <em>must</em> be valid UTF-8. (When
|
||
calling from Rust, the type system takes care of this.) When encoding from
|
||
UTF-16, unpaired surrogates in the input are treated as U+FFFD REPLACEMENT
|
||
CHARACTERS. Therefore, in order for astral characters not to turn into a
|
||
pair of REPLACEMENT CHARACTERS, the caller must ensure that surrogate pairs
|
||
are not split across input buffer boundaries.</p>
|
||
<p>After an <code>encode_*</code> call returns, the output produced so far, taken as a
|
||
whole from the start of the stream, is guaranteed to consist of a valid
|
||
byte sequence in the target encoding. (I.e. the code unit sequence for a
|
||
character is guaranteed not to be split across output buffers. However, due
|
||
to the stateful nature of ISO-2022-JP, the stream needs to be considered
|
||
from the start for it to be valid. For other encodings, the validity holds
|
||
on a per-output buffer basis.)</p>
|
||
<p>The boolean argument <code>last</code> indicates that the end of the stream is reached
|
||
when all the characters in <code>src</code> have been consumed. This argument is needed
|
||
for ISO-2022-JP and is ignored for other encodings.</p>
|
||
<p>An <code>Encoder</code> object can be used to incrementally encode a byte stream.</p>
|
||
<p>During the processing of a single stream, the caller must call <code>encode_*</code>
|
||
zero or more times with <code>last</code> set to <code>false</code> and then call <code>encode_*</code> at
|
||
least once with <code>last</code> set to <code>true</code>. If <code>encode_*</code> returns <code>InputEmpty</code>,
|
||
the processing of the stream has ended. Otherwise, the caller must call
|
||
<code>encode_*</code> again with <code>last</code> set to <code>true</code> (or treat an <code>Unmappable</code> result
|
||
as a fatal error).</p>
|
||
<p>Once the stream has ended, the <code>Encoder</code> object must not be used anymore.
|
||
That is, you need to create another one to process another stream.</p>
|
||
<p>When the encoder returns <code>OutputFull</code> or the encoder returns <code>Unmappable</code>
|
||
and the caller does not wish to treat it as a fatal error, the input buffer
|
||
<code>src</code> may not have been completely consumed. In that case, the caller must
|
||
pass the unconsumed contents of <code>src</code> to <code>encode_*</code> again upon the next
|
||
call.</p>
|
||
<h1 id="infinite-loops" class="section-header"><a href="#infinite-loops">Infinite loops</a></h1>
|
||
<p>When converting with a fixed-size output buffer whose size is too small to
|
||
accommodate one character of output, an infinite loop ensues. When
|
||
converting with a fixed-size output buffer, it generally makes sense to
|
||
make the buffer fairly large (e.g. couple of kilobytes).</p>
