Struct protobuf::well_known_types::Option [−][src]
pub struct Option {
pub name: String,
pub value: MessageField<Any>,
pub unknown_fields: UnknownFields,
pub cached_size: CachedSize,
}
Expand description
A protocol buffer option, which can be attached to a message, field, enumeration, etc.
Fields
name: String
The option’s name. For protobuf built-in options (options defined in
descriptor.proto), this is the short name. For example, "map_entry"
.
For custom options, it should be the fully-qualified name. For example,
"google.api.http"
.
value: MessageField<Any>
The option’s value packed in an Any message. If the value is a primitive, the corresponding wrapper type defined in google/protobuf/wrappers.proto should be used. If the value is an enum, it should be stored as an int32 value using the google.protobuf.Int32Value type.
unknown_fields: UnknownFields
cached_size: CachedSize
