Function shlExact [src]

Shifts a left by shift_amt. Returns an error on overflow. shift_amt is unsigned.

Prototype

pub fn shlExact(comptime T: type, a: T, shift_amt: Log2Int(T)) !T

Parameters

T: typea: Tshift_amt: Log2Int(T)

Source

  pub fn shlExact(comptime T: type, a: T, shift_amt: Log2Int(T)) !T {
    if (T == comptime_int) return a << shift_amt;
    const ov = @shlWithOverflow(a, shift_amt);
    if (ov[1] != 0) return error.Overflow;
    return ov[0];
}
