}

A sealed trait to represent valid lengths for a FixedArray.

This is implemented on u32 for non-16 bit platforms, and u16 on all platforms.

Required Associated Constants

const ZERO: Self

const MAX: Self

const DANGLING: Self::NonZero

👎Deprecated:

will be removed in the next major release

Required Associated Types

type NonZero: NonZero<Self>

👎Deprecated:

will be removed in the next major release

type InlineStrRepr: Copy + AsRef<[u8]> + AsMut<[u8]> + Default + TypeSize

Available on crate feature typesize only.

Required Methods

fn to_usize(self) -> usize

Provided Methods

fn from_usize(len: usize) -> Option<Self>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
