Struct Consumed 

pub struct Consumed<T> {
    pub value: T,
    pub bytes_consumed: usize,
}

A value of type T along with how many bytes were consumed to produce it.

Fields

value: T

The parsed value.

bytes_consumed: usize

Number of bytes read from the stream.

Implementations

impl<T> Consumed<T>

pub fn new(value: T, bytes_consumed: usize) -> Self

Create a new Consumed<T> with the given value and bytes_consumed.

Examples

use crabstep::deserializer::consumed::Consumed;
let consumed = Consumed::new(42, 2);

assert_eq!(consumed.value, 42);
assert_eq!(consumed.bytes_consumed, 2);

pub fn map<U, F>(self, f: F) -> Consumed<U>

where F: FnOnce(T) -> U,

Transform the contained value to another type, preserving bytes_consumed.

Examples

use crabstep::deserializer::consumed::Consumed;
let consumed = Consumed::new(2u8, 1);
let mapped = consumed.map(|v| v as u16);

assert_eq!(mapped.value, 2u16);
assert_eq!(mapped.bytes_consumed, 1);

Trait Implementations

impl<T> Deref for Consumed<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T> DerefMut for Consumed<T>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
