Struct packable::unpacker::CounterUnpacker

source · [−]

pub struct CounterUnpacker<U: Unpacker> { /* private fields */ }

Expand description

An Unpacker able to keep count of the number of read bytes.

Implementations

source

impl<U: Unpacker> CounterUnpacker

source

pub fn new(unpacker: U) -> Self

Creates a new CounterUnpacker.

source

pub fn counter(&self) -> usize

Returns the number of read bytes.

source

pub fn into_inner(self) -> U

Consumes the value to return the inner Unpacker.

Trait Implementations

source

impl<U: Unpacker> Unpacker for CounterUnpacker

type Error = ::Error

An error type representing any error related to reading bytes.

source

fn unpack_bytes<B: AsMut<[u8 ]>>(&mut self, bytes: B) -> Result<(), Self::Error>

Reads a sequence of bytes from the Unpacker. This sequence must be long enough to fill bytes completely. This method must fail if the unpacker does not have enough bytes to fulfill the request. Read more

source

fn ensure_bytes(&self, len: usize) -> Result<(), Self::Error>

Tries to guarantee that the Unpacker has at least len bytes. Read more

source

fn read_bytes(&self) -> Option<usize>

Returns the exact number of read bytes if possible.
