Enum ReadEvalEncodePolicy 

pub enum ReadEvalEncodePolicy {
    Forbid,
    AllowExplicit {
        expected_shape: Symbol,
        allowed_capabilities: Vec<CapabilityName>,
    },
}

Whether read-eval output may be emitted.

Variants

Forbid

Forbid read-eval output.

AllowExplicit

Allow only explicitly declared read-eval output.

The shape and capability fields describe the expected admitted result and maximum powers for the eval body. Codecs must not treat this as a broad permission to emit arbitrary read-eval syntax.

Fields

expected_shape: Symbol

Shape symbol the evaluated result must satisfy.

allowed_capabilities: Vec<CapabilityName>

Maximum capabilities the emitted eval body may request.
