Struct protobuf::well_known_types::Value

pub struct Value {
    pub kind: Option<Kind>,
    pub special_fields: SpecialFields,
}

Value represents a dynamically typed value which can be either null, a number, a string, a boolean, a recursive struct value, or a list of values. A producer of value is expected to set one of these variants. Absence of any variant indicates an error.

The JSON representation for Value is JSON value.

Fields

kind: Option<Kind>

special_fields: SpecialFields
