Struct former::exposed::HashMapDefinition

pub struct HashMapDefinition<K, E, Context = (), Formed = HashMap<K, E>, End = ReturnStorage>
where
    K: Eq + Hash,
    End: FormingEnd<HashMapDefinitionTypes<K, E, Context, Formed>>,
{ /* private fields */ }

Represents the formation definition for a hash map-like collection within the former framework.

This structure defines the essential elements required to form a hash map-like collection, detailing the key and value types, the contextual environment during formation, the final formed type, and the behavior at the end of the formation process. It facilitates customization and extension of hash map formation within any system that implements complex data management operations.

Type Parameters

• K: The key type of the hash map.
• E: The value type of the hash map.
• Context: The optional context provided during the formation process.
• Formed: The type of the entity produced, typically a HashMap<K, E>.
• End: A trait defining the end behavior of the formation process, managing how the hash map is finalized.

Trait Implementations

impl<K, E, Context, Formed, End> Debug for HashMapDefinition<K, E, Context, Formed, End>

where K: Debug + Eq + Hash, E: Debug, Context: Debug, Formed: Debug, End: Debug + FormingEnd<HashMapDefinitionTypes<K, E, Context, Formed>>,

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

Formats the value using the given formatter.

impl<K, E, Context, Formed, End> Default for HashMapDefinition<K, E, Context, Formed, End>

where K: Default + Eq + Hash, E: Default, Context: Default, Formed: Default, End: Default + FormingEnd<HashMapDefinitionTypes<K, E, Context, Formed>>,

fn default() -> HashMapDefinition<K, E, Context, Formed, End>

Returns the “default value” for a type.

impl<K, E, Context, Formed, End> FormerDefinition for HashMapDefinition<K, E, Context, Formed, End>

where K: Eq + Hash, End: FormingEnd<HashMapDefinitionTypes<K, E, Context, Formed>>,

type Storage = HashMap<K, E>

The storage type used during the formation.

type Formed = Formed

The type of the entity being formed. It is generally the structure for which the Former is derived, representing the fully formed state of the entity. However, it can differ if a custom FormingEnd or a different Formed type is defined to handle specific forming logic or requirements.

type Context = Context

The context used during the formation process.

type Types = HashMapDefinitionTypes<K, E, Context, Formed>

Encapsulates the types related to the formation process including any mutators.

type End = End

Defines the ending condition or operation of the formation process.
