Struct NetworkSnapshot 

pub struct NetworkSnapshot { /* private fields */ }

Immutable versioned view of a links network.

Implementations

impl NetworkSnapshot

pub fn new( version: u64, network: LinkNetwork, provenance: impl Into<String>, ) -> Self

Creates an immutable snapshot from a network value.

pub const fn version(&self) -> u64

Snapshot version.

pub const fn parent_version(&self) -> Option<u64>

Parent version when this snapshot was committed from a mutable snapshot.

pub fn provenance(&self) -> &str

Human-readable change provenance for this snapshot.

pub fn network(&self) -> &LinkNetwork

Immutable network data held by this snapshot.

pub fn shared_snapshot_count(&self) -> usize

Number of immutable snapshot handles sharing the same network value.

pub fn from_read_only( version: u64, view: &ReadOnlyNetwork, provenance: impl Into<String>, ) -> Self

Builds an immutable snapshot from a frozen read-only view.

The read-only view’s Arc<LinkNetwork> is reused directly, so freezing and snapshot versioning share one network allocation.

pub fn as_read_only(&self) -> ReadOnlyNetwork

Returns a read-only view sharing this snapshot’s network allocation.

pub fn structural_diff(&self, other: &Self) -> StructuralDiff

Computes changed, added, and removed link ids against another snapshot.

pub fn to_mutable( &self, provenance: impl Into<String>, ) -> MutableNetworkSnapshot

Creates an editable snapshot fork from this immutable snapshot.

Trait Implementations

impl Clone for NetworkSnapshot

fn clone(&self) -> NetworkSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NetworkSnapshot

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

Formats the value using the given formatter.

impl PartialEq for NetworkSnapshot

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