Struct pencil::datastructures::MultiDict

pub struct MultiDict<T> {
    // some fields omitted
}

This is used to deal with multiple values for the same key.

Methods

impl<T> MultiDict<T>

fn new() -> MultiDict<T>

fn get(&self, key: &str) -> Option<&T>

Return the first value for this key.

fn set(&mut self, key: &str, value: T)

Removes an existing key first and add the value.

fn add(&mut self, key: String, value: T)

Adds a new value for the key.

fn getlist(&self, key: &str) -> Option<&Vec<T>>

Return the list of items for a given key.

fn iter<'a>(&'a self) -> MultiDictIter<'a, T>

An iterator of (key, value) pairs. The value will be first value of each key.

fn listiter<'a>(&'a self) -> Iter<'a, String, Vec<T>>

An iterator of (key, values) pairs.

fn keys<'a>(&'a self) -> Keys<'a, String, Vec<T>>

An iterator visiting all keys in arbitrary order.

fn values<'a>(&'a self) -> MultiDictValues<'a, T>

An iterator of the first value on every key's value list.

fn listvalues<'a>(&'a self) -> Values<'a, String, Vec<T>>

An iterator of all values corresponding to a key.

Trait Implementations

impl<T: Clone> Clone for MultiDict<T>

fn clone(&self) -> MultiDict<T>

Returns a copy of the value.

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

Performs copy-assignment from source.
