Implementations

impl LiteralClass

pub fn check( self, lit: &Lit, attr: impl ToString, arg: impl ToString, ) -> Result<(), Error>

Checks the literal against current requirements, generating Error if the requirements are not met.

Trait Implementations

impl Clone for LiteralClass

fn clone(&self) -> LiteralClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LiteralClass

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

Formats the value using the given formatter.

impl From<&Lit> for LiteralClass

fn from(lit: &Lit) -> Self

Converts to this type from the input type.

impl From<Lit> for LiteralClass

fn from(lit: Lit) -> Self

Converts to this type from the input type.

impl From<LiteralClass> for ValueClass

fn from(cls: LiteralClass) -> Self

Converts to this type from the input type.

impl Hash for LiteralClass

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 Ord for LiteralClass

fn cmp(&self, other: &LiteralClass) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LiteralClass

fn eq(&self, other: &LiteralClass) -> 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.

impl PartialOrd for LiteralClass

fn partial_cmp(&self, other: &LiteralClass) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Copy for LiteralClass

impl Eq for LiteralClass

impl StructuralPartialEq for LiteralClass

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
