Enum FieldValue 

pub enum FieldValue {
    Json(Value),
    Binary(Bytes),
}

A single value being matched or generated at the field/element level - the driver-side counterpart of the proto FieldValue.

Binary-safe by construction: a value that is not representable as text is carried as bytes rather than being stringified into one. Scalar types survive the trip to a plugin intact, including the difference between a whole number and a decimal, which the integer, decimal and type matching rules all depend on - see FieldValue::to_proto.

Variants

Json(Value)

A JSON-like value

Binary(Bytes)

Raw bytes, for a value that is not representable as JSON

Implementations

impl FieldValue

pub fn to_proto(&self) -> ProtoFieldValue

Convert to the protobuf form sent to a plugin or core handler.

Each scalar type gets its own arm, so a matching rule on the other side sees the type the value actually has - in particular a whole number stays whole, which integer, decimal and type all depend on. Only maps and lists go across as a google.protobuf.Value.

pub fn from_proto(value: &ProtoFieldValue) -> FieldValue

Convert from the protobuf form returned by a plugin or core handler. An unset value is treated as null, matching how an absent oneof reads everywhere else in the interface.
