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
Returns a new Initializer which will zero out buffers.
unsafe fn nop() -> Initializer
Returns a new Initializer which will not zero out buffers.
Unsafety
This may only be called by Readers 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
Indicates if a buffer should be initialized.
fn initialize(&self, buf: &mut [u8])
Initializes a buffer if necessary.
