Struct bytecodec::Eos

pub struct Eos(_);

Eos contains information on the distance to the end of a stream.

Methods

impl Eos

pub fn new(is_eos_reached: bool) -> Self

Makes a new Eos instance.

pub fn with_remaining_bytes(n: ByteCount) -> Self

Makes a new Eos instance that has the given information about the number of remaining bytes in a stream.

pub fn is_reached(&self) -> bool

Returns true if the target stream has reached to the end, otherwise false.

pub fn remaining_bytes(&self) -> ByteCount

Returns the information about the number of bytes remaining in the target stream.

pub fn back(&self, bytes: u64) -> Self

Returns a new Eos instance that has moved backward from the end of the target stream by the specified number of bytes.

Examples

use bytecodec::{ByteCount, Eos};

let eos = Eos::new(true);
assert_eq!(eos.is_reached(), true);
assert_eq!(eos.remaining_bytes(), ByteCount::Finite(0));

let eos = eos.back(5);
assert_eq!(eos.is_reached(), false);
assert_eq!(eos.remaining_bytes(), ByteCount::Finite(5));
