Struct GraphMutation 

#[repr(C)]
pub struct GraphMutation {
    pub kind: GraphMutationKind,
    pub node_a: u64,
    pub node_b: u64,
    pub weight_fp: i32,
    pub partition_hint: u32,
}

A graph mutation request.

Graph mutations are passed to graph_apply_proved and require a valid proof token to execute.

Fields

kind: GraphMutationKind

The kind of mutation.

node_a: u64

Source node ID (for edge operations) or target node ID.

node_b: u64

Destination node ID (for edge operations).

weight_fp: i32

Edge weight (for AddEdge and UpdateEdgeWeight). Represented as fixed-point: weight * 10000.

partition_hint: u32

Partition ID hint (for coherence routing).

Implementations

impl GraphMutation

pub const fn add_node(node_id: u64) -> Self

Creates an AddNode mutation.

pub const fn remove_node(node_id: u64) -> Self

Creates a RemoveNode mutation.

pub const fn add_edge(from: u64, to: u64, weight: f32) -> Self

Creates an AddEdge mutation.

pub const fn remove_edge(from: u64, to: u64) -> Self

Creates a RemoveEdge mutation.

pub const fn update_edge_weight(from: u64, to: u64, weight: f32) -> Self

Creates an UpdateEdgeWeight mutation.

pub fn weight(&self) -> f32

Returns the weight as a float.

pub const fn with_partition_hint(self, partition_id: u32) -> Self

Sets a partition hint for coherence-aware routing.

Trait Implementations

impl Clone for GraphMutation

fn clone(&self) -> GraphMutation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphMutation

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

Formats the value using the given formatter.

impl Default for GraphMutation

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for GraphMutation

fn eq(&self, other: &GraphMutation) -> 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 Copy for GraphMutation

impl StructuralPartialEq for GraphMutation
