Struct packable::packer::CounterPacker

source · [−]

pub struct CounterPacker<P: Packer> { /* private fields */ }

Expand description

A Packer able to keep count of the number of written bytes.

Implementations

source

impl<P: Packer> CounterPacker

source

pub fn new(packer: P) -> Self

Creates a new CounterPacker.

source

pub fn counter(&self) -> usize

Returns the number of written bytes.

source

pub fn into_inner(self) -> P

Consumes the value to return the inner Packer.

Trait Implementations

source

impl<P: Packer> Packer for CounterPacker

type Error = ::Error

An error type representing any error related to writing bytes.

source

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

Writes a sequence of bytes into the Packer. The totality of bytes must be written into the packer. This method must fail if the packer does not have enough space to fulfill the request. Read more

source

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

Returns the exact number of written bytes if possible.
