Struct borsh::maybestd::io::Initializer[−][src]

pub struct Initializer(_);
🔬 This is a nightly-only experimental API. (read_initializer)

A type used to conditionally initialize buffers passed to Read methods.

Implementations

impl Initializer[src]

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)

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]

🔬 This is a nightly-only experimental API. (read_initializer)

Indicates if a buffer should be initialized.

pub fn initialize(&self, buf: &mut [u8])[src]

🔬 This is a nightly-only experimental API. (read_initializer)

Initializes a buffer if necessary.
