Struct digest::core_api::XofReaderCoreWrapper

pub struct XofReaderCoreWrapper<T> where
    T: XofReaderCore,
    T::BlockSize: IsLess<U256>,
    Le<T::BlockSize, U256>: NonZero,  { /* fields omitted */ }

This is supported on crate feature core-api only.

Wrapper around XofReaderCore implementations.

It handles data buffering and implements the mid-level traits.

Trait Implementations

impl<T: Clone> Clone for XofReaderCoreWrapper<T> where
    T: XofReaderCore,
    T::BlockSize: IsLess<U256>,
    Le<T::BlockSize, U256>: NonZero,
    T::BlockSize: Clone, 

fn clone(&self) -> XofReaderCoreWrapper<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Debug for XofReaderCoreWrapper<T> where
    T: XofReaderCore + AlgorithmName,
    T::BlockSize: IsLess<U256>,
    Le<T::BlockSize, U256>: NonZero, 

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<T: Default> Default for XofReaderCoreWrapper<T> where
    T: XofReaderCore,
    T::BlockSize: IsLess<U256>,
    Le<T::BlockSize, U256>: NonZero,
    T::BlockSize: Default, 

fn default() -> XofReaderCoreWrapper<T>

Returns the “default value” for a type.

impl<T> Read for XofReaderCoreWrapper<T> where
    T: XofReaderCore,
    T::BlockSize: IsLess<U256>,
    Le<T::BlockSize, U256>: NonZero, 

This is supported on crate feature std only.

fn read(&mut self, buf: &mut [u8]) -> Result<usize>

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

fn is_read_vectored(&self) -> bool

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

Determines if this Reader has an efficient read_vectored implementation.

unsafe fn initializer(&self) -> Initializer

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

Determines if this Reader can work with buffers of uninitialized memory.

fn read_to_end(&mut self, buf: &mut Vec<u8, Global>) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until EOF in this source, appending them to buf.

fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Read the exact number of bytes required to fill buf.

fn by_ref(&mut self) -> &mut Self

Creates a “by reference” adapter for this instance of Read.

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an Iterator over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R> where
    R: Read, 

Creates an adapter which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

Creates an adapter which will read at most limit bytes from it.

impl<T> XofReader for XofReaderCoreWrapper<T> where
    T: XofReaderCore,
    T::BlockSize: IsLess<U256>,
    Le<T::BlockSize, U256>: NonZero, 

fn read(&mut self, buffer: &mut [u8])

Read output into the buffer. Can be called an unlimited number of times.

fn read_boxed(&mut self, n: usize) -> Box<[u8]>

This is supported on crate feature alloc only.

Read output into a boxed slice of the specified size.
