Struct neon::prelude::BinaryData[][src]

#[repr(C)]
pub struct BinaryData<'a> { /* fields omitted */ }

A reference to the internal backing buffer data of a Buffer or ArrayBuffer object, which can be accessed via the Borrow and BorrowMut traits.

Methods

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

Produces an immutable slice as a view into the contents of this buffer.

Example:

let b: Handle<JsArrayBuffer> = cx.argument(0)?;
let (x, y) = cx.borrow(&b, |data| {
    let slice = data.as_slice::<i32>();
    (slice[0], slice[1])
});

Produces a mutable slice as a view into the contents of this buffer.

Example:

let mut b: Handle<JsArrayBuffer> = cx.argument(0)?;
cx.borrow_mut(&mut b, |data| {
    let slice = data.as_mut_slice::<f64>();
    slice[0] /= 2.0;
    slice[1] *= 2.0;
});

Produces the length of the buffer, in bytes.
