Struct LanguageId 

pub struct LanguageId(/* private fields */);

A language’s stable identifier, as written in a rule’s language field.

Deliberately not an enum. An enum would have to live in this crate and name every language, so adding one would mean editing the abstraction rather than adding an implementor — exactly the coupling the trait exists to avoid.

Implementations

impl LanguageId

pub const fn new(id: &'static str) -> Self

Declare an identifier. Called by language implementations.

pub const fn as_str(self) -> &'static str

The identifier as it appears in configuration.

Trait Implementations

impl Ord for LanguageId

fn cmp(&self, other: &LanguageId) -> 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.

impl PartialEq for LanguageId

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for LanguageId

fn partial_cmp(&self, other: &LanguageId) -> 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
