Struct cov::intern::Symbol

pub struct Symbol(_);

A handle to an interned string in an Interner.

Symbol is a wrapper of usize, and can be cheaply copied and compared. Symbols are produced by calling Interner::intern().

Trait Implementations

impl Copy for Symbol

impl PartialEq for Symbol

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

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

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

This method tests for !=.

impl Eq for Symbol

impl PartialOrd for Symbol

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

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

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

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

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

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

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

impl Ord for Symbol

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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,

Feeds a slice of this type into the given [Hasher].

impl Default for Symbol

fn default() -> Symbol

Returns the "default value" for a type.
