Function copy [src]

Copies the value of a Const to an existing Mutable so that they both have the same value. Asserts the value fits in the limbs buffer.

Prototype

pub fn copy(self: *Mutable, other: Const) void

Parameters

self: *Mutableother: Const

Source

  pub fn copy(self: *Mutable, other: Const) void {
    if (self.limbs.ptr != other.limbs.ptr) {
        @memcpy(self.limbs[0..other.limbs.len], other.limbs[0..other.limbs.len]);
    }
    // Normalize before setting `positive` so the `eqlZero` doesn't need to iterate
    // over the extra zero limbs.
    self.normalize(other.limbs.len);
    self.positive = other.positive or other.eqlZero();
}
