Struct futures::io::Initializer

pub struct Initializer(_);

A type used to conditionally initialize buffers passed to AsyncRead methods, modeled after std.

Methods

impl Initializer

pub fn zeroing() -> Initializer

Returns a new Initializer which will zero out buffers.

pub unsafe fn nop() -> Initializer

Returns a new Initializer which will not zero out buffers.

Safety

This method may only be called by AsyncReaders which guarantee that they will not read from the buffers passed to AsyncRead methods, and that the return value of the method accurately reflects the number of bytes that have been written to the head of the buffer.

pub fn should_initialize(&self) -> bool

Indicates if a buffer should be initialized.

pub fn initialize(&self, buf: &mut [u8])

Initializes a buffer if necessary.

Trait Implementations

impl Debug for Initializer

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.
