Struct former::exposed::FormingEndClosure
source · pub struct FormingEndClosure<Definition>where
Definition: FormerDefinitionTypes,{ /* private fields */ }
Expand description
A wrapper around a closure to be used as a FormingEnd
.
This struct allows for dynamic dispatch of a closure that matches the
FormingEnd
trait’s call
method signature. It is useful for cases where
a closure needs to be stored or passed around as an object implementing
FormingEnd
.
Implementations§
source§impl<Definition> FormingEndClosure<Definition>where
Definition: FormerDefinitionTypes,
impl<Definition> FormingEndClosure<Definition>where
Definition: FormerDefinitionTypes,
sourcepub fn new(
closure: impl Fn(<Definition as FormerDefinitionTypes>::Storage, Option<<Definition as FormerDefinitionTypes>::Context>) -> <Definition as FormerDefinitionTypes>::Formed + 'static,
) -> FormingEndClosure<Definition>
pub fn new( closure: impl Fn(<Definition as FormerDefinitionTypes>::Storage, Option<<Definition as FormerDefinitionTypes>::Context>) -> <Definition as FormerDefinitionTypes>::Formed + 'static, ) -> FormingEndClosure<Definition>
Constructs a new FormingEndClosure
with the provided closure.
§Parameters
closure
- A closure that matches the expected signature for transforming a collection and context into a new context. This closure is stored and called by thecall
method of theFormingEnd
trait implementation.
§Returns
Returns an instance of FormingEndClosure
encapsulating the provided closure.

impl<C, E> EntryToVal<C> for Ewhere

§type Val = <C as Collection>::Val
type Val = <C as Collection>::Val
The type of values stored in the collection. This might be distinct from
Entry
in complex collections.
For example, in a HashMap
, while Entry
might be a ( key, value ) tuple, Val
might only be the value part.source§fn entry_to_val(self) -> <E as EntryToVal<C>>::Val
fn entry_to_val(self) -> <E as EntryToVal<C>>::Val
Converts an entry into a value representation specific to the type of collection. This conversion is crucial
for handling operations on entries, especially when they need to be treated or accessed as individual values,
such as retrieving the value part from a key-value pair in a hash map.

source§fn val_to_entry(self) -> <C as CollectionValToEntry<Val>>::Entry
fn val_to_entry(self) -> <C as CollectionValToEntry<Val>>::Entry
Invokes the val_to_entry
function of the CollectionValToEntry
trait to convert the value to an entry.
§type Entry = <C as CollectionValToEntry<Val>>::Entry
type Entry = <C as CollectionValToEntry<Val>>::Entry
Represents the type of entry that corresponds to the value within the collection.
