[−][src]Struct neon::types::BinaryData
A reference to the internal backing buffer data of a Buffer
or ArrayBuffer
object, which can be accessed via the Borrow
and BorrowMut
traits.
Implementations
impl<'a> BinaryData<'a>
[src]
pub fn as_slice<T: BinaryViewType>(self) -> &'a [T]
[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]) });
pub fn as_mut_slice<T: BinaryViewType>(self) -> &'a mut [T]
[src]
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; });
pub fn len(self) -> usize
[src]
Produces the length of the buffer, in bytes.
