[−][src]Struct v4l::buffer::Buffer

pub struct Buffer<'a> { /* fields omitted */ }

Represents a buffer view

Implementations

impl<'a> Buffer<'a>[src]

pub fn new(view: &'a [u8], meta: Metadata) -> Self[src]

Returns a memory region view

Buffers created this way provide read-only access to the backing data, enforcing callers to copy the data before mutating it.

Arguments

  • view - Slice of raw memory
  • meta - Metadata, usually filled in by the driver

Example

use v4l::{buffer, timestamp};

let data: Vec<u8> = Vec::new();
let ts = timestamp::Timestamp::new(0 /* sec */, 0 /* usec */);
let flags = buffer::Flags::from(0);
let meta = buffer::Metadata::new(0, ts, flags);
let buf = buffer::Buffer::new(&data, meta);

pub fn data(&self) -> &[u8][src]

Slice of read-only data

pub fn meta(&self) -> &Metadata[src]

Metadata such as allocation flags, timestamp and more
