[−][src]Struct v4l::buffer::StreamItem

pub struct StreamItem<'a, T> { /* fields omitted */ }

Stream item wrapper

The sole purpose of this wrapper struct is to attach a lifetime to values of type T. This is especially useful for volatile types such as views which provide access to some kind of underlying data.

Implementations

impl<'a, T> StreamItem<'a, T>[src]

pub fn new(item: T) -> Self[src]

Returns a wrapped stream item by moving it into the wrapper

An explicit lifetime is attached automatically by inserting PhantomData.

Arguments

  • item - Item to be wrapped

Example

use std::ops::Deref;
use v4l::buffer::StreamItem;

let item: u32 = 123;
let wrapper = StreamItem::new(item);
assert_eq!(*wrapper.deref(), item);
