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