Struct ListByRelayIds 

pub struct ListByRelayIds<H: HasRelayIds>
where
    RsaIdentity: Hash + Eq + Clone,
    Ed25519Identity: Hash + Eq + Clone,
{ /* private fields */ }

A list of objects that can be accessed by relay identity.

Multiple objects in the list can have a given relay identity.

Invariants

Every object in the list must have at least one recognized relay identity; if it does not, it cannot be inserted.

This list may panic or give incorrect results if the values can change their keys through interior mutability.

General information

A list of elements of type H whose members can be accessed by multiple keys.

The keys are:

• rsa (RsaIdentity) (Option)
• ed25519 (Ed25519Identity) (Option)

Each element has a value for each required key, and up to one value for each optional key. There can be many elements for a given key value.

Requirements

Key types must have consistent Hash and Eq implementations, as they will be used as keys in a HashMap.

If all keys are optional, then every element inserted must have at least one non-None key.

An element must not change its keys over time through interior mutability.

If any of these rules is violated, the consequences are unspecified, and could include panics or wrong answers (but not memory-unsafety).

Try to insert value.

Return Error::NoKeys if all the keys are optional, and value has no keys at all.

pub fn insert(&mut self, value: H)

See try_insert. Panicks on errors.

pub fn len(&self) -> usize

pub fn capacity(&self) -> usize

Return the number of elements for which this container has allocated storage.

pub fn retain<F>(&mut self, pred: F)

where F: FnMut(&H) -> bool,

Remove every element that does not satisfy the predicate pred.

impl<H: HasRelayIds> ListByRelayIds<H>

pub fn by_id<'a, T>(&self, key: T) -> ListByRelayIdsIter<'_, H>

where T: Into<RelayIdRef<'a>>,

Returns an empty iterator if key has no relay IDs.

pub fn all_overlapping<T>(&self, key: &T) -> Vec<&H>

where T: HasRelayIds,

Return a reference to every element in this set that shares any ID with key.

No element is returned more than once. Equality is compared using ByAddress.

pub fn all_subset<T>(&self, key: &T) -> Vec<&H>

where T: HasRelayIds,

Return a reference to every element in this list whose relay IDs are a subset of the relay IDs that key has.

No element is returned more than once. Equality is compared using ByAddress.

pub fn remove_by_id<'a, T>( &mut self, key: T, filter: impl FnMut(&H) -> bool, ) -> Vec<H>

where T: Into<RelayIdRef<'a>>,

Return the values in this list that have the key key and where filter returns true.

pub fn remove_exact<T>(&mut self, key: &T) -> Vec<H>

where T: HasRelayIds,

Remove and return the values in this list that have exactly the same relay IDs that key does.

pub fn remove_by_all_ids<T>(&mut self, key: &T) -> Vec<H>

where T: HasRelayIds,

Remove and return the values in this list that have all the same relay IDs that key does.

If key has no relay IDs, then no values are removed.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
