Struct modalkit::editing::completion::CompletionMap

pub struct CompletionMap<K, V>
where
    K: AsRef<str> + Clone + Eq,
{ /* private fields */ }

Maps keys onto values with support for listing keys by prefix.

Implementations

impl<K, V> CompletionMap<K, V>

where K: AsRef<str> + Clone + Eq,

pub fn is_empty(&self) -> bool

Whether this completer contains zero completions.

pub fn insert(&mut self, k: K, v: V) -> Option<V>

Map the given key onto the given value.

pub fn remove<Q>(&mut self, k: &Q) -> Option<V>

where Q: AsRef<str> + ?Sized,

Unmap the given key, returning its previous value if one existed.

pub fn get<Q>(&self, k: &Q) -> Option<&V>

where Q: AsRef<str> + ?Sized,

Get an immutable reference to a value if the key exists.

pub fn get_mut<Q>(&mut self, k: &Q) -> Option<&mut V>

where Q: AsRef<str> + ?Sized,

Get a mutable reference to a value if the key exists.

pub fn get_or_default(&mut self, k: K) -> &mut V

where V: Default,

Get a mutable reference to a value for the given key.

If the key is unmapped, then this will insert a Default value first.

pub fn complete(&self, prefix: &str) -> Vec<K>

Get a list of keys that share a common prefix.
