Struct former_runtime::HashmapFormer

pub struct HashmapFormer<K, E, Hashmap, Former, ContainerEnd> where
    K: Eq + Hash,
    Hashmap: HashmapLike<K, E> + Default,
    ContainerEnd: Fn(&mut Former, Option<Hashmap>),  { /* fields omitted */ }

Class for forming hashmap-like fields.

Implementations

impl<K, E, Hashmap, Former, ContainerEnd> HashmapFormer<K, E, Hashmap, Former, ContainerEnd> where
    K: Eq + Hash,
    Hashmap: HashmapLike<K, E> + Default,
    ContainerEnd: Fn(&mut Former, Option<Hashmap>), 

pub fn new(
    former: Former,
    container: Option<Hashmap>,
    on_end: ContainerEnd
) -> Self

Make a new HashmapFormer. It should be called by a former generated for your structure.

pub fn replace(self, vector: Hashmap) -> Self

Set the whole container instead of setting each element individually.

pub fn end(self) -> Former

Return former of your struct moving container there. Should be called after configuring the container.

pub fn insert<K2, E2>(self, k: K2, e: E2) -> Self where
    K2: Into<K>,
    E2: Into<E>, 

Inserts a key-value pair into the map. Make a new container if it was not made so far.
