[−][src]Struct stdweb::UnsafeTypedArray
A wrapper type for exposing raw Rust slices as TypedArray
s
at zero cost without copying.
The only thing you can do with this is to pass it to the js!
macro.
Using this is highly unsafe! After you pass it to the js!
macro
you must use it before triggering any Rust code whatsoever,
either directly or indirectly. Breaking this rule will result
in undefined behavior!
Examples
let slice: &[u8] = &[1, 2, 3]; let slice = unsafe { UnsafeTypedArray::new( slice ) }; js!( var slice = @{slice}; // `slice` is an Uint8Array var sum = slice[0] + slice[1] + slice[2]; console.log( "Sum of array elements: ", sum ); );
Methods
impl<'a, T> UnsafeTypedArray<'a, T>
[src]
pub unsafe fn new(slice: &'a [T]) -> Self
[src]
Creates a new UnsafeTypedArray
.
Even though this function is marked as unsafe
the unsafely only comes into play after you
pass it to the js!
macro.
