Trait BytesSeek 

pub trait BytesSeek {
    // Required methods
    fn position(&self) -> usize;
    fn try_seek(&mut self, pos: usize) -> Result<(), SeekError>;

    // Provided methods
    fn seek(&mut self, pos: usize) { ... }
    fn try_advance(&mut self, adv: usize) -> Result<(), SeekError> { ... }
    fn advance(&mut self, adv: usize) { ... }
}

Sets the internal position for writing or reading.

Required Methods

fn position(&self) -> usize

Returns the internal position.

fn try_seek(&mut self, pos: usize) -> Result<(), SeekError>

Sets the internal position if possible.

Provided Methods

fn seek(&mut self, pos: usize)

Sets the internal position.

fn try_advance(&mut self, adv: usize) -> Result<(), SeekError>

Advances the internal position if possible.

fn advance(&mut self, adv: usize)

Advances the internal position.

Panic

May panic depending on the BytesSeek::seek implementation.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
