Struct astral::string::StringId

pub struct StringId(_);

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);

Methods

impl StringId

pub fn new<S>(
    string: S,
    subsystem: &Subsystem<BuildHasherDefault<Murmur3>>
) -> StringId 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 Copy for StringId

impl Eq for StringId

impl PartialEq<StringId> for StringId

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

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

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

This method tests for !=.

impl Debug for StringId

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

Formats the value using the given formatter.

impl Hash for StringId

fn hash<__H>(&self, state: &mut __H) where
    __H: Hasher, 

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 Clone for StringId

fn clone(&self) -> StringId

Returns a copy of the value.

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

Performs copy-assignment from source.
