sourcepub fn get(&self, key: &str) -> Option<&str>
pub fn get(&self, key: &str) -> Option<&str>
Get the value of an element of this Map
, or None
if it doesn’t contain key
sourcepub fn insert<K, V>(&mut self, key: K, value: V)where
K: Into<Cow<'a, str>>,
V: Into<Cow<'a, str>>,
pub fn insert<K, V>(&mut self, key: K, value: V)where K: Into<Cow<'a, str>>, V: Into<Cow<'a, str>>,
Insert a new element in this Map
Overwrites elements with the same key
, if present.
