[][src]Struct scale_info::interner::Interner

pub struct Interner<T> { /* fields omitted */ }

Interning data structure generic over the element type.

For the sake of simplicity and correctness we are using a rather naive implementation.

Usage

This is used in order to quite efficiently cache strings and type definitions uniquely identified by their associated type identifiers.

Implementations

impl<T> Interner<T> where
    T: Ord
[src]

pub fn new() -> Self[src]

Creates a new empty interner.

impl<T> Interner<T> where
    T: Ord + Clone
[src]

pub fn intern_or_get(&mut self, s: T) -> (bool, Symbol<'_, T>)[src]

Interns the given element or returns its associated symbol if it has already been interned.

pub fn get(&self, s: &T) -> Option<Symbol<'_, T>>[src]

Returns the symbol of the given element or None if it hasn't been interned already.

pub fn resolve(&self, sym: Symbol<'_, T>) -> Option<&T>[src]

Resolves the original element given its associated symbol or returns None if it has not been interned yet.
