Enum Entry 

pub enum Entry<In, Name> {
    In(In),
    Name(Name),
}

This represents either an entry name, or the name of the thing that the entry is in (for instance the name of a pallet or of a Runtime API trait).

Iterators returning this will iterate containers in order, first returning Entry::In to communicate which container (eg pallet or Runtime API trait) is being iterated over next, and then a Entry::Names for the name of each of the entries in the given container.

A container name will not be handed back more than once.

Variants

In(In)

The name of the thing that the following entries are in/under.

Name(Name)

The name of the entry in/under the last given Entry::In.

Implementations

impl<T> Entry<T, T>

pub fn map<R, F: FnOnce(T) -> R>(self, f: F) -> Entry<R, R>

Map the values in the entry, assuming they are the same.

impl<In, Name> Entry<In, Name>

pub fn entries_in( entries: impl Iterator<Item = Entry<In, Name>>, container: impl PartialEq<In>, ) -> impl Iterator<Item = Name>

where In: PartialEq, Name: PartialEq,

Iterate over all of the entries in a specific container (ie all of the entries which follow a specific Entry::In).

pub fn tuples_of( entries: impl Iterator<Item = Entry<In, Name>>, ) -> impl Iterator<Item = (In, Name)>

where In: Clone,

Iterate over all of the entries, returning tuples of (entry_in, entry_name). This can be easier to work with in some cases.

Trait Implementations

impl<In: Clone, Name: Clone> Clone for Entry<In, Name>

fn clone(&self) -> Entry<In, Name>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<In: Debug, Name: Debug> Debug for Entry<In, Name>

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

Formats the value using the given formatter.

impl<In: Hash, Name: Hash> Hash for Entry<In, Name>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<In: Ord, Name: Ord> Ord for Entry<In, Name>

fn cmp(&self, other: &Entry<In, Name>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<In: PartialEq, Name: PartialEq> PartialEq for Entry<In, Name>

fn eq(&self, other: &Entry<In, Name>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<In: PartialOrd, Name: PartialOrd> PartialOrd for Entry<In, Name>

fn partial_cmp(&self, other: &Entry<In, Name>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
