Struct PlanKey 

pub struct PlanKey { /* private fields */ }

The identity of one lowered plan: every input that determines it.

The three semantics of the contract are separate fields, so an entry lowered under one engine semantics can never be served under another, and a caller cannot reach a key by hashing something: the fields are typed values, not strings to concatenate.

Implementations

impl PlanKey

pub fn new( definition_revision: DefinitionRevision, compiler_semantics: CompilerSemantics, engine_semantics: EngineSemantics, lowering_capabilities: LoweringCapabilities, ) -> PlanKey

pub fn for_definition( definition: &WorkflowDefinition, compiler_semantics: CompilerSemantics, engine_semantics: EngineSemantics, lowering_capabilities: LoweringCapabilities, ) -> Result<PlanKey, PlanInputError>

The key one definition has under one semantics configuration.

pub fn definition_revision(&self) -> &DefinitionRevision

pub fn compiler_semantics(&self) -> CompilerSemantics

pub fn engine_semantics(&self) -> EngineSemantics

pub fn lowering_capabilities(&self) -> &LoweringCapabilities

pub fn canonical_bytes(&self, identity: &PlanIdentity) -> Vec<u8>

The canonical encoding of every field, in fixed order, under the binding-identity schema identity binds. Validated tags cannot contain the separators, so the encoding is unambiguous.

pub fn binding_digest(&self, identity: &PlanIdentity) -> String

The stable identity of this plan under identity’s lines.

It is derived from the key alone, so rebuilding a plan that a cache evicted reproduces this value instead of minting a new one, and a run bound to it stays bound. Two identities digest the same key differently on purpose: their persisted records must never alias.

Trait Implementations

impl Clone for PlanKey

fn clone(&self) -> PlanKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PlanKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PlanKey

fn deserialize<__D>( __deserializer: __D, ) -> Result<PlanKey, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for PlanKey

impl From<&PlanKey> for RecordedPlanKey

fn from(key: &PlanKey) -> RecordedPlanKey

Records under Acativa’s own identity lines. A host binding other lines calls RecordedPlanKey::record with its PlanIdentity.

impl Hash for PlanKey

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 Ord for PlanKey

fn cmp(&self, other: &PlanKey) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for PlanKey

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for PlanKey

fn partial_cmp(&self, other: &PlanKey) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for PlanKey

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
