Trait Resolver 

pub trait Resolver<Key: InternKey = TokenKey> {
    // Required method
    fn try_resolve(&self, key: Key) -> Option<&str>;

    // Provided method
    fn resolve(&self, key: Key) -> &str { ... }
}

The read-only part of an interner. Allows to perform lookups of intern keys to resolve them to their interned text.

Required Methods

fn try_resolve(&self, key: Key) -> Option<&str>

Tries to resolve the given key and return its interned text.

If self does not contain any text for key, None is returned.

Provided Methods

fn resolve(&self, key: Key) -> &str

Resolves key to its interned text.

Panics

Panics if there is no text for key.

Compatibility implementations for interners from other crates may also panic if key cannot be converted to the key type of the external interner. Please ensure you configure any external interners appropriately (for example by choosing an appropriately sized key type).
