Trait ValidatedPayload 

pub trait ValidatedPayload: Payload {
    // Provided method
    fn validate_value(value: &Value) -> Result<(), ValidationError> { ... }
}

Available on crate feature validate only.

A payload type whose original JSON Schema is embedded at compile time and available for runtime validation.

Implemented automatically by the codegen for every generated request and response payload type.

Provided Methods

fn validate_value(value: &Value) -> Result<(), ValidationError>

Validate value against Payload::PAYLOAD_SCHEMA.

Returns ValidationError with the collected schema-validation errors when the value does not conform. Where the payload type carries no schema (PAYLOAD_SCHEMA is None — the hand-modelled trust-task-error), there is nothing to check and this succeeds: the Rust type the value deserialized into is itself the constraint.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors

impl<P> ValidatedPayload for P

where P: Payload,

Every Payload is validatable, because every Payload carries its schema (or states that it has none).

Before 0.9.0 this trait declared its own SCHEMA_JSON const and the codegen emitted one impl per generated type. The schema now lives on Payload itself — reachable without the validate feature, since a &'static str costs nothing — and this blanket impl replaces roughly three hundred generated impl blocks.
