Expand description
Trait for unsigned integers that can be indexed with.
Always smaller than or equal to usize
.
Required Associated Types§
type FixedWidth: Index
type FixedWidth: Index
Equally-sized index type with a fixed size (no usize
).
type Signed: SignedIndex
type Signed: SignedIndex
Equally-sized signed index type.
Provided Methods§
fn canonicalize(slice: &[Self]) -> &[Self::FixedWidth]
fn canonicalize(slice: &[Self]) -> &[Self::FixedWidth]
Convert a reference to a slice of Self
to fixed width types.
fn canonicalize_mut(slice: &mut [Self]) -> &mut [Self::FixedWidth]
fn canonicalize_mut(slice: &mut [Self]) -> &mut [Self::FixedWidth]
Convert a mutable reference to a slice of Self
to fixed width types.
fn from_signed(value: Self::Signed) -> Self
fn from_signed(value: Self::Signed) -> Self
Convert a signed value to an unsigned one.
fn sum_nonnegative(slice: &[Self]) -> Option<Self>
fn sum_nonnegative(slice: &[Self]) -> Option<Self>
Sum values while checking for overflow.
