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