Struct Edges 

pub struct Edges { /* private fields */ }

A container for edge envelopes on a document.

Edges stores pre-constructed edge envelopes keyed by their digest, mirroring the Attachments container but for edges as defined in BCR-2026-003.

Implementations

impl Edges

pub fn new() -> Self

Creates a new empty edges container.

pub fn add(&mut self, edge_envelope: Envelope)

Adds a pre-constructed edge envelope.

pub fn get(&self, digest: Digest) -> Option<&Envelope>

Retrieves an edge by its digest.

pub fn remove(&mut self, digest: Digest) -> Option<Envelope>

Removes an edge by its digest.

pub fn clear(&mut self)

Removes all edges from the container.

pub fn is_empty(&self) -> bool

Returns whether the container has any edges.

pub fn len(&self) -> usize

Returns the number of edges in the container.

pub fn iter(&self) -> impl Iterator<Item = (&Digest, &Envelope)>

Returns an iterator over all edge envelopes.

pub fn add_to_envelope(&self, envelope: Envelope) -> Envelope

Adds all edges as 'edge' assertion envelopes to the given envelope.

pub fn try_from_envelope(envelope: &Envelope) -> Result<Edges>

Extracts edges from an envelope’s 'edge' assertions.

Trait Implementations

impl Clone for Edges

fn clone(&self) -> Edges

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Edges

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

Formats the value using the given formatter.

impl Default for Edges

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Edges

fn eq(&self, other: &Edges) -> 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.
