Struct StringId

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

An opaque struct for fast comparison between strings.

StringId represents a unique identifier to a string.

Example

use astral::string::StringId;

let id1 = StringId::new("foo", &string_subsystem);
let id2 = StringId::new("bar", &string_subsystem);
let id3 = StringId::new("foo", &string_subsystem);

assert_ne!(id1, id2);
assert_eq!(id1, id3);

Implementations

impl StringId

pub fn new<S>(string: S, subsystem: &Subsystem) -> Self

where S: AsRef<str>,

Construcs a new StringId from the given string in the specified Subsystem.

If the string was used before, the StringId will be equal.

Example

Trait Implementations

impl Clone for StringId

fn clone(&self) -> StringId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StringId

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

Formats the value using the given formatter.

impl Hash for StringId

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 StringId

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