Struct fast_rustc_ap_rustc_span::symbol::SymbolStr

pub struct SymbolStr { /* fields omitted */ }

An alternative to Symbol, useful when the chars within the symbol need to be accessed. It deliberately has limited functionality and should only be used for temporary values.

Because the interner outlives any thread which uses this type, we can safely treat string which points to interner data, as an immortal string, as long as this type never crosses between threads.

Trait Implementations

impl Clone for SymbolStr

fn clone(&self) -> SymbolStr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SymbolStr

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

Formats the value using the given formatter.

impl Deref for SymbolStr

This impl means that if ss is a SymbolStr:

• *ss is a str;
• &*ss is a &str;
• &ss as &str is a &str, which means that &ss can be passed to a function expecting a &str.

type Target = str

The resulting type after dereferencing.

fn deref(&self) -> &str

Dereferences the value.

impl Display for SymbolStr

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

Formats the value using the given formatter.

impl Eq for SymbolStr

impl<CTX> HashStable<CTX> for SymbolStr

fn hash_stable(&self, hcx: &mut CTX, hasher: &mut StableHasher)

impl Ord for SymbolStr

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

This method returns an [Ordering] between self and other.

#[must_use] fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use] fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use] fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl<T: Deref<Target = str>> PartialEq<T> for SymbolStr

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

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

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<SymbolStr> for SymbolStr

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

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

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

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

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

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

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

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

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

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