[−][src]Struct futures_util::io::Initializer
🔬 This is a nightly-only experimental API. (
read_initializer
)This is supported on crate features
io
and read-initializer
only.A type used to conditionally initialize buffers passed to Read
methods.
Implementations
impl Initializer
[src]
pub fn zeroing() -> Initializer
[src]
🔬 This is a nightly-only experimental API. (
read_initializer
)Returns a new Initializer
which will zero out buffers.
pub unsafe fn nop() -> Initializer
[src]
🔬 This is a nightly-only experimental API. (
read_initializer
)Returns a new Initializer
which will not zero out buffers.
Safety
This may only be called by Read
ers which guarantee that they will not
read from buffers passed to Read
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]
🔬 This is a nightly-only experimental API. (
read_initializer
)Indicates if a buffer should be initialized.
pub fn initialize(&self, buf: &mut [u8])
[src]
🔬 This is a nightly-only experimental API. (
read_initializer
)Initializes a buffer if necessary.
