Struct sp_runtime::traits::TrailingZeroInput

pub struct TrailingZeroInput<'a>(_);

Input that adds infinite number of zero after wrapped input.

Implementations

impl<'a> TrailingZeroInput<'a>

pub fn new(data: &'a [u8]) -> Self

Create a new instance from the given byte array.

Trait Implementations

impl<'a> Input for TrailingZeroInput<'a>

fn remaining_len(&mut self) -> Result<Option<usize>, Error>

Should return the remaining length of the input data. If no information about the input length is available, None should be returned.

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

Read the exact number of bytes required to fill the given buffer.

fn read_byte(&mut self) -> Result<u8, Error>

Read a single byte from the input.

fn descend_ref(&mut self) -> Result<(), Error>

Descend into nested reference when decoding. This is called when decoding a new refence-based instance, such as Vec or Box. Currently all such types are allocated on the heap.

fn ascend_ref(&mut self)

Ascend to previous structure level when decoding. This is called when decoding reference-based type is finished.
