Required Methods§
sourcefn mul_add_assign(&mut self, a: Self, b: Self)
fn mul_add_assign(&mut self, a: Self, b: Self)
Replaces self with self + a * b.
sourcefn from_le_bytes(bytes: &[u8]) -> Self
fn from_le_bytes(bytes: &[u8]) -> Self
Reads a Number from little endian bytes.
sourcefn to_le_bytes(self) -> Vec<u8>
fn to_le_bytes(self) -> Vec<u8>
Converts a Number to little endian bytes.
sourcefn from_be_bytes(bytes: &[u8]) -> Self
fn from_be_bytes(bytes: &[u8]) -> Self
Reads a Number from big endian bytes.
sourcefn to_be_bytes(self) -> Vec<u8>
fn to_be_bytes(self) -> Vec<u8>
Converts a Number to big endian bytes.
sourcefn epsilon() -> Self
fn epsilon() -> Self
Returns the epsilon value for the type.
For floating point types, this is the difference between 1.0 and the next largest representable number.
For integer types, this is 0.
sourcefn next_random<R: Rng>(rng: &mut R) -> Self
fn next_random<R: Rng>(rng: &mut R) -> Self
Returns a random Number.
