Struct Symbol 

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

A symbol is an interned string.

Implementations

impl Symbol

pub const fn new(n: u32) -> Self

pub fn intern(string: impl ToString) -> Self

Maps a string to its interned representation.

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

pub fn as_u32(self) -> u32

pub fn as_usize(self) -> usize

pub fn is_keyword(self) -> bool

Returns true if this symbol is a keyword in the IR textual format

Trait Implementations

impl AsRef<str> for Symbol

fn as_ref(&self) -> &str

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Symbol

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Symbol

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

Formats the value using the given formatter.

impl From<&'static str> for Symbol

fn from(s: &'static str) -> Self

Converts to this type from the input type.

impl From<Box<str>> for Symbol

fn from(s: Box<str>) -> Self

Converts to this type from the input type.

impl From<CompactString> for Symbol

fn from(s: CompactString) -> Self

Converts to this type from the input type.

impl From<Cow<'static, str>> for Symbol

fn from(s: Cow<'static, str>) -> Self

Converts to this type from the input type.

impl From<String> for Symbol

fn from(s: String) -> Self

Converts to this type from the input type.

impl Hash for Symbol

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,

Feeds a slice of this type into the given Hasher.

impl Ord for Symbol

fn cmp(&self, other: &Self) -> 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<T: Deref<Target = str>> PartialEq<T> for Symbol

fn eq(&self, other: &T) -> 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 PartialEq for Symbol

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

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

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.

impl Serialize for Symbol

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
