Trait cstree::interning::Resolver[−][src]

pub trait Resolver<K = Spur> {
    pub fn resolve(&'a self, key: &K) -> &'a str;

    pub fn try_resolve(&'a self, key: &K) -> Option<&'a str>;

    pub unsafe fn resolve_unchecked(&'a self, key: &K) -> &'a str;

    pub fn contains_key(&self, key: &K) -> bool;

    pub fn len(&self) -> usize;

    pub fn is_empty(&self) -> bool { ... }
}

A generic interface that allows using any underlying interner only for its resolution capabilities, allowing only key -> str lookups

Required methods

pub fn resolve(&'a self, key: &K) -> &'a str[src]

Resolves the given key into a string

Panics

Panics if the key is not contained in the current Resolver

pub fn try_resolve(&'a self, key: &K) -> Option<&'a str>[src]

Attempts to resolve the given key into a string, returning None if it cannot be found

pub unsafe fn resolve_unchecked(&'a self, key: &K) -> &'a str[src]

Resolves a string by its key without preforming bounds checks

Safety

The key must be valid for the current Resolver

pub fn contains_key(&self, key: &K) -> bool[src]

Returns true if the current interner contains the given key

pub fn len(&self) -> usize[src]

Gets the number of currently interned strings
