Enum Identifier 

pub enum Identifier {
    Named(MetaString),
    Numeric(usize),
}

An identifier used to key values in a DataspaceRegistry.

Identifiers come in two flavors:

• Named: a string-based identifier, using [MetaString] for efficient storage.
• Numeric: a simple numeric identifier.

Variants

Named(MetaString)

A string-based identifier.

Numeric(usize)

A numeric identifier.

Implementations

impl Identifier

pub fn named(name: impl Into<MetaString>) -> Self

Creates a named identifier.

pub fn numeric(id: usize) -> Self

Creates a numeric identifier.

Trait Implementations

impl Clone for Identifier

fn clone(&self) -> Identifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Identifier

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

Formats the value using the given formatter.

impl From<&str> for Identifier

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<Id> for Identifier

fn from(id: Id) -> Self

Converts to this type from the input type.

impl From<MetaString> for Identifier

fn from(s: MetaString) -> Self

Converts to this type from the input type.

impl From<usize> for Identifier

fn from(id: usize) -> Self

Converts to this type from the input type.

impl Hash for Identifier

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 PartialEq for Identifier

fn eq(&self, other: &Identifier) -> 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.
