Implementations

impl AsPathSegment

pub fn sequence<S: AsRef<[u32]>>(seq: S) -> Self

Shorthand for creating an AsSequence segment.

pub fn set<S: AsRef<[u32]>>(seq: S) -> Self

Shorthand for creating an AsSet segment.

pub fn route_len(&self) -> usize

Get the number of ASNs this segment adds to the route. For the number of ASNs within the segment use AsPathSegment::len instead.

pub fn len(&self) -> usize

Ge the total number of ASNs within this segment. For the number of ASNs this segment adds to a packet’s route, use AsPathSegment::route_len instead.

pub fn is_empty(&self) -> bool

Returns true if this segment has a length of 0.

pub fn iter(&self) -> <&Self as IntoIterator>::IntoIter

Get an iterator over the ASNs within this path segment

pub fn iter_mut(&mut self) -> <&mut Self as IntoIterator>::IntoIter

Get a mutable iterator over the ASNs within this path segment

pub fn is_confed(&self) -> bool

Gets if a segment represents the local members of an autonomous system confederation. Shorthand for matches!(x, AsPathSegment::ConfedSequence(_) | AsPathSegment::ConfedSet(_)).

Trait Implementations

impl AsRef<[Asn]> for AsPathSegment

fn as_ref(&self) -> &[Asn]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for AsPathSegment

fn clone(&self) -> AsPathSegment

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AsPathSegment

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

Formats the value using the given formatter.

impl Hash for AsPathSegment

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<'a> IntoIterator for &'a AsPathSegment

type Item = &'a Asn

The type of the elements being iterated over.

type IntoIter = Iter<'a, Asn>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'a> IntoIterator for &'a mut AsPathSegment

type Item = &'a mut Asn

The type of the elements being iterated over.

type IntoIter = IterMut<'a, Asn>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl IntoIterator for AsPathSegment

type Item = Asn

The type of the elements being iterated over.

type IntoIter = IntoIter<Asn>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for AsPathSegment

Check for equality of two path segments.

let a = AsPathSegment::sequence([1, 2, 3]);
let b = AsPathSegment::set([1, 2, 3]);

// Sequences must be identical to be considered equivalent
assert_eq!(a, AsPathSegment::sequence([1, 2, 3]));
assert_ne!(a, AsPathSegment::sequence([1, 2, 3, 3]));

// Sets may be reordered, but must contain exactly the same ASNs.
assert_eq!(b, AsPathSegment::set([3, 1, 2]));
assert_ne!(b, AsPathSegment::set([1, 2, 3, 3]));

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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