Expand description

A Resolver that uses an in memory map to lookup entries

Implementations§

Source§

impl MapResolver

Source

pub fn insert(&self, k: String, v: String) -> Option<String>

Inserts a key-value pair into the map.

Source

pub fn get(&self, k: &str) -> Option<String>

Returns the value corresponding to the key

Source

pub fn remove(&self, k: &str) -> Option<String>

Removes a key from the map, returning the value at the key if the key was previously in the map.
