Struct ProjectionProviderDescriptorV1 

pub struct ProjectionProviderDescriptorV1 { /* private fields */ }

One fixed-size compiler-owned provider contract.

Implementations

impl ProjectionProviderDescriptorV1

pub fn new( kind: ProjectionProviderKindV1, posture: ProjectionProviderPostureV1, capabilities: ProjectionProviderCapabilitiesV1, policy_mode: ProjectionProviderPolicyModeV1, bounds: ProjectionProviderStaticBoundsV1, state: ProjectionProviderStateIdentityV1, ) -> Result<Self, ProjectionProviderValidationError>

Constructs and validates a sealed descriptor.

pub fn from_canonical_bytes( bytes: &[u8], ) -> Result<Self, ProjectionProviderValidationError>

Decodes and strictly validates one canonical V1 descriptor.

pub fn to_canonical_bytes(&self) -> [u8; 112]

Encodes the exact canonical fixed-size V1 form.

pub fn digest(&self) -> ProjectionProviderDescriptorHash

Returns the exact descriptor digest.

pub const fn kind(&self) -> ProjectionProviderKindV1

Provider family pinned by the compiler.

pub const fn posture(&self) -> ProjectionProviderPostureV1

Exactness posture pinned by the compiler.

pub const fn capabilities(&self) -> ProjectionProviderCapabilitiesV1

Closed supported capabilities.

pub const fn aggregate_semantics(&self) -> AggregateSemanticSetV1

Exact aggregate semantic subset implemented by this provider.

A generic MEASURE stage is insufficient to prove a particular fold; this closed subset prevents a compiler from treating the union of real providers as capabilities of any one provider.

pub const fn policy_mode(&self) -> ProjectionProviderPolicyModeV1

Ranked authorization-shaping mode.

pub const fn freshness(&self) -> ProjectionProviderFreshnessV1

Exact retained-epoch freshness model.

pub const fn lifecycle(&self) -> ProjectionProviderLifecycleModelV1

Rebuildable provider-generation lifecycle model.

pub const fn static_bounds(&self) -> ProjectionProviderStaticBoundsV1

Complete static cost and retention bounds.

pub const fn max_candidates(&self) -> u32

Maximum candidates before any result shaping.

pub const fn max_output_rows(&self) -> u32

Maximum result rows.

pub const fn max_measures(&self) -> u16

Maximum whole-set measures/facets.

pub const fn retained_epochs(&self) -> u64

Minimum retained epoch count promised by the provider.

pub const fn max_catchup_lag(&self) -> u64

Maximum admitted catch-up lag before health degrades.

pub const fn max_epoch_lease_steps(&self) -> u64

Maximum deterministic epoch-lease lifetime retained for continuations.

pub const fn state_identity(&self) -> ProjectionProviderStateIdentityV1

Immutable provider-state schema identity.
