Enum PrepareError 

pub enum PrepareError {
    SourceBinding(String),
    MissingBackend(String),
    DescriptorMismatch {
        backend_id: String,
    },
    HardBudgetUnenforceable {
        backend_id: String,
        model: CostModel,
    },
    SinkVersionUnsupported {
        schema: &'static str,
    },
    StoreMissing,
    StoreContractMismatch,
}

Why a plan cannot run on this runtime (spec 003, 3.5.3 and 3.6.5).

Variants

SourceBinding(String)

MissingBackend(String)

The plan binds a backend id that is not registered.

DescriptorMismatch

The registered backend’s descriptor is not the one the plan bound.

Fields

backend_id: String

HardBudgetUnenforceable

A hard budget, and a reachable backend without enforceable bounds.

Fields

backend_id: String

model: CostModel

SinkVersionUnsupported

A plan 3 and an evidence sink that does not accept rustev.run/3 (spec 032, 3.11.2).

Fields

schema: &'static str

StoreMissing

A persistent tier, and a runtime built without a store (spec 044, 3.4.1).

StoreContractMismatch

The store’s contract is not the one the plan states.
