Struct GraphEntityKey 

pub struct GraphEntityKey { /* private fields */ }

Stable project-qualified key for one graph entity.

Implementations

impl GraphEntityKey

pub fn new(project: ProjectInstanceId, selector: &EntitySelector) -> Self

Derive a stable key from a project and typed selector.

pub const fn project(&self) -> ProjectInstanceId

Return the owning project instance.

pub fn digest(&self) -> &str

Borrow the lowercase compact digest.

pub fn digest_bytes(&self) -> Result<[u8; 32], GraphContractError>

Return the compact binary digest used by normalized persistence.

Errors

Returns GraphContractError::InvalidStableKeyDigest if the private key invariant was violated by incompatible persisted input.

pub fn canonical_identity(&self) -> &str

Borrow the canonical identity retained for collision detection.

pub fn reconcile(&self, other: &Self) -> Result<bool, GraphContractError>

Determine whether two keys identify the same entity, failing on collision.

Errors

Returns GraphContractError::StableKeyCollision when equal digests retain different canonical identities.

Trait Implementations

impl Clone for GraphEntityKey

fn clone(&self) -> GraphEntityKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphEntityKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for GraphEntityKey

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for GraphEntityKey

fn eq(&self, other: &GraphEntityKey) -> 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 Serialize for GraphEntityKey

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
