Struct ShiftLeftStatic

pub struct ShiftLeftStatic<const N: u8>;

Shift left for unsigned 128-bit integers, with the shift amount specified at compile time.

The shift amount N must be in range 0..=32.

Behavior

BEFORE: _ [v: u128]
AFTER:  _ [v << SHIFT_AMOUNT: u128]

Preconditions

• input argument arg is properly BFieldCodec encoded

Postconditions

• the output is properly BFieldCodec encoded

impl<const N: u8> Hash for ShiftLeftStatic<N>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl<const N: u8> PartialEq for ShiftLeftStatic<N>

fn eq(&self, other: &ShiftLeftStatic<N>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
