Struct nom_grapheme_clusters::span::Symbol

pub struct Symbol<T> {
    pub span: Span,
    pub data: T,
}

A type for metadata associated with a span (“spanned data”).

Fields

span: Span

The span from which metadata comes from.

data: T

Metadata produced from the span.

Implementations

impl<T> Symbol<T>

pub fn as_ref(&self) -> Symbol<&T>

Helper method to make symbol reference to data.

pub fn as_mut(&mut self) -> Symbol<&mut T>

Helper method to make symbol mutably reference to data.

pub fn map<F, U>(self, mapper: F) -> Symbol<U>where F: FnOnce(T) -> U,

Helper method to convert data.

Trait Implementations

impl<T> Borrow<T> for Symbol<T>

fn borrow(&self) -> &T

Immutably borrows from an owned value.

impl<T: Clone> Clone for Symbol<T>

fn clone(&self) -> Symbol<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Symbol<T>

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

Formats the value using the given formatter.

impl<T> Hash for Symbol<T>where T: Hash,

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

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<T> Ord for Symbol<T>where T: Ord,

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl<T> PartialEq<Symbol<T>> for Symbol<T>where T: PartialEq,

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<T> PartialEq<T> for Symbol<T>where T: PartialEq,

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<T> PartialOrd<Symbol<T>> for Symbol<T>where T: PartialOrd,

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl<T> PartialOrd<T> for Symbol<T>where T: PartialOrd,

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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