Struct linux_video_core::BufferData

pub struct BufferData<'r, Dir, Met: Method> { /* private fields */ }

Implementations

impl<'r, Met: Method> BufferData<'r, Out, Met>

pub fn set_len(&mut self, len: usize)

Set new size of buffer

New size should be less than or equal to capacity. If new size greater than capacity it will be set to be equal to capacity.

impl<'r, Dir, Met: Method> BufferData<'r, Dir, Met>

pub fn is_empty(&self) -> bool

Check no used bytes in buffer

pub fn len(&self) -> usize

Get used data of buffer in bytes

pub fn capacity(&self) -> usize

Get available buffer capacity in bytes

Methods from Deref<Target = Buffer>

pub fn timestamp<T: IsTimestamp>(&self) -> T

pub fn set_timestamp<T: IsTimestamp>(&mut self, time: T)

Set timestamp

pub fn has_timecode(&self) -> bool

Buffer has time code

pub fn timecode(&self) -> Option<TimeCode>

Buffer time code

pub fn set_timecode(&mut self, timecode: Option<TimeCode>)

Trait Implementations

impl<'r, Met: Method> AsMut<[u8]> for BufferData<'r, Out, Met>

fn as_mut(&mut self) -> &mut [u8]

Converts this type into a mutable reference of the (usually inferred) input type.

impl<'r, Dir, Met: Method> AsRef<[u8]> for BufferData<'r, Dir, Met>

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl<'r, Dir, Met: Method> Deref for BufferData<'r, Dir, Met>
