Struct EngineSemantics 

pub struct EngineSemantics(/* private fields */);

A version of this crate’s engine semantics line: how a lowered plan executes.

Same shape and same guarantee as CompilerSemantics: engine behavior has versions, and a definition digest is not one of them.

Implementations

impl EngineSemantics

pub const CURRENT: EngineSemantics

The semantics this build executes.

pub fn version( identity: &PlanIdentity, version: u16, ) -> Result<EngineSemantics, PlanInputError>

Name a version of the engine semantics line identity binds.

pub fn generic_version(version: u16) -> Result<EngineSemantics, PlanInputError>

version under Acativa’s own identity lines — the generic dialect.

pub const fn version_of(self) -> u16

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

The recorded form under identity’s lines: acativa.workflow.engine.v1 for ACATIVA_PLAN_IDENTITY.

pub fn generic_wire(self) -> String

The recorded form under Acativa’s own identity lines.

pub fn from_wire( identity: &PlanIdentity, value: &str, ) -> Result<EngineSemantics, PlanInputError>

pub fn generic_from_wire(value: &str) -> Result<EngineSemantics, PlanInputError>

from_wire under Acativa’s own identity lines.

Trait Implementations

impl Clone for EngineSemantics

fn clone(&self) -> EngineSemantics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for EngineSemantics

impl Debug for EngineSemantics

impl<'de> Deserialize<'de> for EngineSemantics

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for EngineSemantics

impl Hash for EngineSemantics

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 EngineSemantics

fn cmp(&self, other: &EngineSemantics) -> 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 EngineSemantics

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for EngineSemantics

fn partial_cmp(&self, other: &EngineSemantics) -> 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

impl Serialize for EngineSemantics

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.

impl StructuralPartialEq for EngineSemantics

impl TryFrom<u16> for EngineSemantics

fn try_from( version: u16, ) -> Result<EngineSemantics, <EngineSemantics as TryFrom<u16>>::Error>

Names a version of Acativa’s own engine line. A host binding other lines calls EngineSemantics::version with its PlanIdentity.

type Error = PlanInputError

The type returned in the event of a conversion error.
