impl Float16Array

pub fn new_from_u16_slice(slice: &[u16]) -> Float16Array

Creates an array from raw IEEE 754 binary16 bit patterns.

This pairs naturally with the optional half crate:

use half::f16;
use js_sys::Float16Array;

let values = [f16::from_f32(1.0), f16::from_f32(-2.0)];
let bits = values.map(f16::to_bits);
let array = Float16Array::new_from_u16_slice(&bits);

pub fn copy_to_u16_slice(&self, dst: &mut [u16])

Copy the raw IEEE 754 binary16 bit patterns from this JS typed array into the destination Rust slice.

Panics

This function will panic if this typed array’s length is different than the length of the provided dst array.

Values copied into dst can be converted back into half::f16 with half::f16::from_bits.

pub fn copy_from_u16_slice(&self, src: &[u16])

Copy raw IEEE 754 binary16 bit patterns from the source Rust slice into this JS typed array.

Panics

This function will panic if this typed array’s length is different than the length of the provided src array.

When using the optional half crate, populate src with half::f16::to_bits().

pub fn to_u16_vec(&self) -> Vec<u16>

Efficiently copies the contents of this JS typed array into a new Vec of raw IEEE 754 binary16 bit patterns.

This makes it easy to round-trip through the optional half crate:

use half::f16;

let bits = array.to_u16_vec();
let values: Vec<f16> = bits.into_iter().map(f16::from_bits).collect();
