Struct SizedSequence

pub struct SizedSequence<T, S, F>(pub F, pub T)
where
    T: IntoIterator,
    T::Item: WriteInto,
    T::IntoIter: ExactSizeIterator,
    S: WriteInto,
    F: FnOnce(usize) -> S;

Used to write values from IntoIterator with known size.

Example

use write_into::{BigEndian, SizedSequence, write_into};

let mut buffer = Vec::new();
let written = write_into(&mut buffer, SizedSequence(|size| BigEndian(size as u16), &[
    BigEndian(0xAABBu16),
    BigEndian(0xCCDDu16),
])).unwrap();
assert_eq!(written, 2);
assert_eq!(&buffer, &[0x00, 0x02, 0xAA, 0xBB, 0xCC, 0xDD]);

Trait Implementations

impl<T, S, F> WriteInto for &SizedSequence<T, S, F>

where T: Copy + IntoIterator, T::Item: WriteInto, T::IntoIter: ExactSizeIterator, S: WriteInto, F: Copy + FnOnce(usize) -> S,

Returns how many items was written.

type Output = usize

Result of WriteInto::write_into function (e.g. () or usize).

fn write_into(self, sink: &mut impl Write) -> Result<Self::Output>

Writes value into I/O sink.

impl<T, S, F> WriteInto for SizedSequence<T, S, F>

where T: IntoIterator, T::Item: WriteInto, T::IntoIter: ExactSizeIterator, S: WriteInto, F: FnOnce(usize) -> S,

Returns how many items was written.

type Output = usize

Result of WriteInto::write_into function (e.g. () or usize).

fn write_into(self, sink: &mut impl Write) -> Result<Self::Output>

Writes value into I/O sink.
