Struct query_map::QueryMap

source · [−]

pub struct QueryMap(_);

Expand description

A read-only view into a map of data which may contain multiple values

Internally data is always represented as many values

Implementations

source

impl QueryMap

source

pub fn first(&self, key: &str) -> Option<&str>

Return the first elelemnt associated with a key

source

pub fn all(&self, key: &str) -> Option<Vec<&str>>

Return all elements associated with a key

source

pub fn is_empty(&self) -> bool

Return true if there are no elements in the map

source

pub fn iter(&self) -> QueryMapIter<'_>ⓘNotable traits for QueryMapIter<'a>`impl<'a> Iterator for QueryMapIter<'a> type Item = (&'a str, &'a str);`

Return an iterator for this map
