Struct VecInput 

pub struct VecInput { /* private fields */ }

A wrapper that implements Input for Vec<u8>.

Implementations

impl VecInput

pub fn new(buf: Vec<u8>) -> Self

Creates new input from the provided vector.

pub fn is_empty(&self) -> bool

Returns true if there are no remaining bytes left.

pub fn into_inner(self) -> Vec<u8>

Returns underlying vector.

Trait Implementations

impl Input for VecInput

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

Read a single byte from the input.

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

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

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.

fn on_before_alloc_mem(&mut self, _size: usize) -> Result<(), Error>

Hook that is called before allocating memory on the heap.
