# Struct openssl::asn1::Asn1StringRef [−] [src]

    pub struct Asn1StringRef(_);

Reference to `Asn1String`

## Implementations

### `impl Asn1StringRef` [src]

#### `pub fn as_utf8(&self) -> Result<OpensslString, ErrorStack>` [src]

Converts the ASN.1 underlying format to UTF8

ASN.1 strings may utilize UTF-16, ASCII, BMP, or UTF8. This is important to consume the string in a meaningful way without knowing the underlying format.

#### `pub fn as_slice(&self) -> &[u8]ⓘ

### Notable traits for &'_ [u8]

`impl<'_> Read for &'_ [u8]impl<'_> Write for &'_ mut [u8]`
` [src]

Return the string as an array of bytes.

The bytes do not directly correspond to UTF-8 encoding. To interact with strings in rust, it is preferable to use `as_utf8`

#### `pub fn len(&self) -> usize` [src]

Returns the number of bytes in the string.

#### `pub fn is_empty(&self) -> bool` [src]

Determines if the string is empty.
