Trait nannou::prelude::identities::Zero

pub trait Zero: Add<Self, Output = Self> {
    pub fn zero() -> Self;
    pub fn is_zero(&self) -> bool;

    pub fn set_zero(&mut self) { ... }
}

Defines an additive identity element for Self.

Laws

a + 0 = a       ∀ a ∈ Self
0 + a = a       ∀ a ∈ Self

Required methods

pub fn zero() -> Self

Returns the additive identity element of Self, 0.

Purity

This function should return the same result at all times regardless of external mutable state, for example values stored in TLS or in static muts.

pub fn is_zero(&self) -> bool

Returns true if self is equal to the additive identity.

pub fn set_zero(&mut self)

Sets self to the additive identity element of Self, 0.
