Enum ConstantValue

Typed constant value.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ConstantValue

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<&[u32]> for ConstantValue

fn from(x: &[u32]) -> Self

Converts to this type from the input type.

impl From<&[u8]> for ConstantValue

fn from(x: &[u8]) -> Self

Converts to this type from the input type.

impl From<[u8; 4]> for ConstantValue

fn from(x: [u8; 4]) -> Self

Converts to this type from the input type.

impl From<[u8; 8]> for ConstantValue

fn from(x: [u8; 8]) -> Self

Converts to this type from the input type.

impl From<bool> for ConstantValue

fn from(x: bool) -> Self

Converts to this type from the input type.

impl From<f32> for ConstantValue

fn from(x: f32) -> Self

Converts to this type from the input type.

impl From<i32> for ConstantValue

fn from(x: i32) -> Self

Converts to this type from the input type.

impl From<u32> for ConstantValue

fn from(x: u32) -> Self

Converts to this type from the input type.

impl Hash for ConstantValue

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ConstantValue

fn eq(&self, other: &ConstantValue) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
