Enum values

Lists the values of one enum type in a pool: the levels a decoded enum field takes as a factor, with their numbers.

Usage

proto_enums(pool, type)

Arguments

pool

A pool from proto_pool().

type

An enum type's full name, such as "google.protobuf.NullValue". proto_fields() gives it as a field's type_name.

Value

A data frame with one row per value, in definition order, and columns name and number. An alias (allow_alias) is a row of its own with the number it shares. R has no integer for -2^31, so that number is NA, with a zuproto_precision_loss warning.

Examples

pool <- proto_pool()
proto_enums(pool, "google.protobuf.Field.Kind")
