Struct RelayIdSet 

pub struct RelayIdSet { /* private fields */ }

A set of relay identities, backed by HashSet.

Note

I’d rather use HashSet entirely, but that doesn’t let us index by RelayIdRef.

Implementations

impl RelayIdSet

pub fn new() -> Self

Construct a new empty RelayIdSet.

pub fn insert<T: Into<RelayId>>(&mut self, key: T) -> bool

Insert key into this set.

Return true if it was not already there.

pub fn remove<'a, T: Into<RelayIdRef<'a>>>(&mut self, key: T) -> bool

Remove key from the set.

Return true if key was present.

pub fn contains<'a, T: Into<RelayIdRef<'a>>>(&self, key: T) -> bool

Return true if key is a member of this set.

pub fn iter(&self) -> impl Iterator<Item = RelayIdRef<'_>>

Return an iterator over the members of this set.

The ordering of the iterator is undefined; do not rely on it.

pub fn len(&self) -> usize

Return the number of keys in this set.

pub fn is_empty(&self) -> bool

Return true if there are not keys in this set.

Trait Implementations

impl Clone for RelayIdSet

fn clone(&self) -> RelayIdSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RelayIdSet

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

Formats the value using the given formatter.

impl Default for RelayIdSet

fn default() -> RelayIdSet

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RelayIdSet

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<ID: Into<RelayId>> Extend<ID> for RelayIdSet

fn extend<T: IntoIterator<Item = ID>>(&mut self, iter: T)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl FromIterator<RelayId> for RelayIdSet

fn from_iter<T: IntoIterator<Item = RelayId>>(iter: T) -> Self

Creates a value from an iterator.

impl PartialEq for RelayIdSet

fn eq(&self, other: &RelayIdSet) -> 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 Serialize for RelayIdSet

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for RelayIdSet

impl StructuralPartialEq for RelayIdSet

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.
