ByteStore

Struct ByteStore 

Source
pub struct ByteStore {
    pub buf: Rc<RefCell<Vec<u8>>>,
    pub off: usize,
    pub len: usize,
    pub kind: u8,
}
Expand description

オブジェクトの種別。Plain 以外は内部表現を持つ。 1 バイト型 TypedArray の記憶域(共有のバイト列のうち off から len バイト)。

Fields§

§buf: Rc<RefCell<Vec<u8>>>§off: usize§len: usize§kind: u8

0 = Uint8、1 = Int8、2 = Uint8Clamped。

Implementations§

Source§

impl ByteStore

Source

pub fn new(bytes: Vec<u8>, kind: u8) -> Self

Source

pub fn view(&self, start: usize, len: usize, kind: u8) -> Self

同じ記憶域の [start, start+len) を指す(subarray)。

Source

pub fn get(&self, i: usize) -> Option<f64>

Source

pub fn set(&self, i: usize, v: f64)

要素型に合わせて変換して書く(Uint8: ToUint8、Int8: ToInt8、Clamped: 丸めて 0..255)。

Source

pub fn coerce(v: f64, kind: u8) -> u8

Source

pub fn to_vec(&self) -> Vec<u8> ⓘ

Source

pub fn values(&self) -> Vec<Value>
