Struct simple_bytes::Cursor

pub struct Cursor<T> { /* private fields */ }

A generic struct implementing BytesRead, BytesWrite and BytesSeek for different types.

In the background Bytes, BytesMut and BytesOwned use this.

Implementations

impl<T> Cursor<T>

pub fn new(inner: T) -> Self

Creates a new Cursor.

pub fn inner(&self) -> &T

Returns the inner value as a reference.

pub fn inner_mut(&mut self) -> &mut T

Returns the inner value as a mutable reference. Shrinking the inner len may lead to panics when reading or writing.

pub fn into_inner(self) -> T

Returns the inner value, discarding how many bytes were read or written.
