Struct Symbol 

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

A interned string in the global symbol table.

This requires the global feature on the crate.

GlobalSymbol is a wrapper around Symbol that knows to refer to a built-in, global SymbolTable. Strings into the global table are never freed.

This enables a lot of convience methods and trait implementations over GlobalSymbol (see below). In particular, you can convert it to &'static str, convert From and Into a &str, and de/serialize using serde if the serde feature is enabled.

Implementations

impl GlobalSymbol

pub fn new(s: impl AsRef<str>) -> GlobalSymbol

Intern a string into the global symbol table.

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

Convert this symbol into the string in the static, global symbol table.

impl FromStr for GlobalSymbol

type Err = Infallible

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<GlobalSymbol, <GlobalSymbol as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for GlobalSymbol

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 LanguageChildren for Symbol

fn all_slot_occurrences_iter_mut(&mut self) -> impl Iterator<Item = &mut Slot>

fn public_slot_occurrences_iter_mut( &mut self, ) -> impl Iterator<Item = &mut Slot>

fn applied_id_occurrences_iter_mut( &mut self, ) -> impl Iterator<Item = &mut AppliedId>

fn all_slot_occurrences_iter(&self) -> impl Iterator<Item = &Slot>

fn public_slot_occurrences_iter(&self) -> impl Iterator<Item = &Slot>

fn applied_id_occurrences_iter(&self) -> impl Iterator<Item = &AppliedId>

fn to_syntax(&self) -> Vec<SyntaxElem>

fn from_syntax(elems: &[SyntaxElem]) -> Option<Self>

fn weak_shape_impl(&mut self, _m: &mut (SlotMap, u32))

impl Ord for GlobalSymbol

fn cmp(&self, other: &GlobalSymbol) -> 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 GlobalSymbol

fn eq(&self, other: &GlobalSymbol) -> 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 GlobalSymbol

fn partial_cmp(&self, other: &GlobalSymbol) -> 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.
