Struct prost_types::Field [−][src]
pub struct Field { pub kind: i32, pub cardinality: i32, pub number: i32, pub name: String, pub type_url: String, pub oneof_index: i32, pub packed: bool, pub options: Vec<Option>, pub json_name: String, pub default_value: String, }
Expand description
A single field of a message type.
Fields
kind: i32
The field type.
cardinality: i32
The field cardinality.
number: i32
The field number.
name: String
The field name.
type_url: String
The field type URL, without the scheme, for message or enumeration
types. Example: "type.googleapis.com/google.protobuf.Timestamp"
.
oneof_index: i32
The index of the field type in Type.oneofs
, for message or enumeration
types. The first type has index 1; zero means the type is not in the list.
packed: bool
Whether to use alternative packed wire representation.
options: Vec<Option>
The protocol buffer options.
json_name: String
The field JSON name.
default_value: String
The string value of the default value of this field. Proto2 syntax only.
Implementations
Returns the enum value of kind
, or the default if the field is set to an invalid enum value.
Returns the enum value of cardinality
, or the default if the field is set to an invalid enum value.
Sets cardinality
to the provided enum value.
