[−][src]Struct futures::io::Initializer
A type used to conditionally initialize buffers passed to AsyncRead
methods, modeled after std.
Methods
impl Initializer[src]
[−]
impl Initializerpub fn zeroing() -> Initializer | [src] |
Returns a new Initializer which will zero out buffers.
pub unsafe fn nop() -> Initializer | [src] |
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 | [src] |
Indicates if a buffer should be initialized.
pub fn initialize(&self, buf: &mut [u8]) | [src] |
Initializes a buffer if necessary.
