Struct Cursor

pub struct Cursor<W>(/* private fields */);

Wrapper around a Write impl that keeps track of the write position.

Implementations

impl<W> Cursor<W>

pub fn new(w: W) -> Self

pub fn position(&self) -> usize

Get the current position.

pub fn get_ref(&self) -> &W

Access the inner writer.

pub fn get_mut(&mut self) -> &mut W

Unique access to the inner writer.

pub fn into_inner(self) -> W

Deconstruct into the inner writer.

Trait Implementations

impl<W: Debug> Debug for Cursor<W>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Write for Cursor<&mut [u8]>

type Error = EndOfSlice

fn write_all(&mut self, buf: &[u8]) -> Result<(), Self::Error>

Write the whole byte slice.

impl<const N: usize> Write for Cursor<[u8; N]>

type Error = EndOfArray

fn write_all(&mut self, buf: &[u8]) -> Result<(), Self::Error>

Write the whole byte slice.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
