Struct Exact 

pub struct Exact<T, const VALUE: i32>(pub T);

An exact value wrapper using const generics.

This wrapper validates that literal values are exactly equal to the specified VALUE at parse time.

Tuple Fields

0: T

Implementations

impl<T, const VALUE: i32> Exact<T, VALUE>

pub fn inner(&self) -> &T

pub fn into_inner(self) -> T

Consumes self and returns the inner value.

Trait Implementations

impl<T: Clone, const VALUE: i32> Clone for Exact<T, VALUE>

fn clone(&self) -> Exact<T, VALUE>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

Formats the value using the given formatter.

impl<T: Into<Cursor>, const VALUE: i32> From<Exact<T, VALUE>> for Cursor

fn from(value: Exact<T, VALUE>) -> Self

Converts to this type from the input type.

impl<T: Hash, const VALUE: i32> Hash for Exact<T, VALUE>

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,

impl<T: Ord, const VALUE: i32> Ord for Exact<T, VALUE>

fn cmp(&self, other: &Exact<T, VALUE>) -> 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<'a, T: Parse<'a> + ToNumberValue, const VALUE: i32> Parse<'a> for Exact<T, VALUE>

fn parse<I>(p: &mut Parser<'a, I>) -> Result<Self>

where I: Iterator<Item = Cursor> + Clone,

impl<T: PartialEq, const VALUE: i32> PartialEq for Exact<T, VALUE>

fn eq(&self, other: &Exact<T, VALUE>) -> 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<T: PartialOrd, const VALUE: i32> PartialOrd for Exact<T, VALUE>

fn partial_cmp(&self, other: &Exact<T, VALUE>) -> 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.
