Struct OriginList 

pub struct OriginList(/* private fields */);

Bounded list of Origin entries, typically the hop chain of a broadcast.

Guarantees len() <= MAX_HOPS. Construct via OriginList::new + OriginList::push, or fall back to the fallible TryFrom<Vec<Origin>>.

Implementations

impl OriginList

pub fn new() -> Self

Create an empty list.

pub fn push(&mut self, origin: Origin) -> Result<(), TooManyOrigins>

Append an Origin. Returns TooManyOrigins if the list is full.

pub fn contains(&self, origin: &Origin) -> bool

Returns true if any entry matches origin.

pub fn len(&self) -> usize

Number of entries currently in the list (always <= MAX_HOPS).

pub fn is_empty(&self) -> bool

Whether the list contains no entries.

pub fn iter(&self) -> Iter<'_, Origin>

Iterate over the entries in hop order (oldest first).

pub fn as_slice(&self) -> &[Origin]

Borrow the entries as a slice.

Trait Implementations

impl Clone for OriginList

fn clone(&self) -> OriginList

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OriginList

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

Formats the value using the given formatter.

impl Default for OriginList

fn default() -> OriginList

Returns the “default value” for a type.

impl<'a> IntoIterator for &'a OriginList

type Item = &'a Origin

The type of the elements being iterated over.

type IntoIter = Iter<'a, Origin>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for OriginList

fn eq(&self, other: &OriginList) -> 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 TryFrom<Vec<Origin>> for OriginList

type Error = TooManyOrigins

The type returned in the event of a conversion error.

fn try_from(v: Vec<Origin>) -> Result<Self, Self::Error>

Performs the conversion.
