Struct reparser::def::io::Initializer [−][src]
pub struct Initializer(_);
🔬 This is a nightly-only experimental API. (
read_initializer
)Expand description
A type used to conditionally initialize buffers passed to Read
methods.
Implementations
impl Initializer
[src]
impl Initializer
[src]pub fn zeroing() -> Initializer
[src]
🔬 This is a nightly-only experimental API. (read_initializer
)
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
)
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.
