Struct HashSetFormer 

pub struct HashSetFormer<E, HashSet, Former, ContainerEnd>
where
    E: Eq + Hash,
    HashSet: HashSetLike<E> + Default,
    ContainerEnd: Fn(&mut Former, Option<HashSet>),
{ /* private fields */ }

Class for forming hashset-like fields.

Implementations

impl<E, HashSet, Former, ContainerEnd> HashSetFormer<E, HashSet, Former, ContainerEnd>

where E: Eq + Hash, HashSet: HashSetLike<E> + Default, ContainerEnd: Fn(&mut Former, Option<HashSet>),

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

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

pub fn replace(self, container: HashSet) -> 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<E2>(self, e: E2) -> Self

where E2: Into<E>,

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

Trait Implementations

impl<E, HashSet, Former: Debug, ContainerEnd> Debug for HashSetFormer<E, HashSet, Former, ContainerEnd>

where E: Eq + Hash + Debug, HashSet: HashSetLike<E> + Default + Debug, ContainerEnd: Fn(&mut Former, Option<HashSet>) + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<E, HashSet, Former: Default, ContainerEnd> Default for HashSetFormer<E, HashSet, Former, ContainerEnd>

where E: Eq + Hash + Default, HashSet: HashSetLike<E> + Default + Default, ContainerEnd: Fn(&mut Former, Option<HashSet>) + Default,

fn default() -> HashSetFormer<E, HashSet, Former, ContainerEnd>

Returns the “default value” for a type.
