Struct former::exposed::NoEnd

source · 
pub struct NoEnd;
Expand description

A placeholder FormingEnd used when no end operation is required or applicable.

This implementation is useful in generic or templated scenarios where a FormingEnd is required by the interface, but no meaningful end operation is applicable. It serves a role similar to core::marker::PhantomData by filling generic parameter slots without contributing operational logic.

Trait Implementations§

Formats the value using the given formatter. Read more

fn default() -> NoEnd

Returns the “default value” for a type. Read more

impl<Definition> FormingEnd<Definition> for NoEnd
where Definition: FormerDefinitionTypes,

source§

fn call( &self, _storage: <Definition as FormerDefinitionTypes>::Storage, _context: Option<<Definition as FormerDefinitionTypes>::Context> ) -> <Definition as FormerDefinitionTypes>::Formed

Intentionally causes a panic if called, as its use indicates a configuration error.

source§

impl<C, E> EntryToVal<C> for E
where C: Collection<Entry = E>,

§

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

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§

impl<T> From<T> for T

source§

fn from(t: T) -> T

Returns the argument unchanged.

source§

impl<T, U> Into<U> for T
where U: From<T>,

source§

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

source§

impl<T, U> TryFrom<U> for T
where U: Into<T>,

§

type Error = Infallible

The type returned in the event of a conversion error.
source§

fn try_from(value: U) -> Result<T, <T as TryFrom<U>>::Error>

Performs the conversion.
source§

impl<T, U> TryInto<U> for T
where U: TryFrom<T>,

§

type Error = <U as TryFrom<T>>::Error

The type returned in the event of a conversion error.
source§

fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>

Performs the conversion.
source§

impl<C, Val> ValToEntry<C> for Val
where C: CollectionValToEntry<Val>,

source§

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

Represents the type of entry that corresponds to the value within the collection.
