# Struct bytes::buf::Limit [−] [src]

    pub struct Limit<T> { /* fields omitted */ }

A `BufMut` adapter which limits the amount of bytes that can be written to an underlying buffer.

## Implementations

### `impl<T> Limit<T>` [src]

#### `pub fn into_inner(self) -> T` [src]

Consumes this `Limit`, returning the underlying value.

#### `pub fn get_ref(&self) -> &T` [src]

Gets a reference to the underlying `BufMut`.

It is inadvisable to directly write to the underlying `BufMut`.

#### `pub fn get_mut(&mut self) -> &mut T` [src]

Gets a mutable reference to the underlying `BufMut`.

It is inadvisable to directly write to the underlying `BufMut`.

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

Returns the maximum number of bytes that can be written

# Note

If the inner `BufMut` has fewer bytes than indicated by this method then that is the actual number of available bytes.

#### `pub fn set_limit(&mut self, lim: usize)` [src]

Sets the maximum number of bytes that can be written.

# Note

If the inner `BufMut` has fewer bytes than `lim` then that is the actual number of available bytes.
