Struct std::io::Initializer [−][src]
A type used to conditionally initialize buffers passed to Read methods.
Implementations
impl Initializer[src]
pub 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 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.
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.
