@protobuf-ts/plugin/build/interpreter.d.ts

The protocol buffer compiler plugin "protobuf-ts" generates TypeScript, gRPC-web, Twirp, and more.

import { DescEnum, DescMessage, DescService, FileRegistry } from "@bufbuild/protobuf";
import * as rt from "@protobuf-ts/runtime";
import * as rpc from "@protobuf-ts/runtime-rpc";
/**
 * The protobuf-ts plugin generates code for message types from descriptor
 * protos. This class also creates message types from descriptor protos, but
 * but instead of generating code, it creates the type in-memory.
 *
 * This means that it is possible, for example, to read a message from binary
 * data without any generated code.
 *
 * The protobuf-ts plugin uses the interpreter to read custom options at
 * compile time and convert them to JSON.
 *
 * Since the interpreter creates fully functional message types including
 * reflection information, the protobuf-ts plugin uses the interpreter as
 * single source of truth for generating message interfaces and reflection
 * information.

     * Returns a map of custom options for the provided descriptor.
     * The map is an object indexed by the extension field name.
     * The value of the extension field is provided in JSON format.
     *
     * This works by:
     * - searching for option extensions for the given descriptor proto
     *   in the registry.
     * - for example, providing a google.protobuf.FieldDescriptorProto
     *   searches for all extensions on google.protobuf.FieldOption.
     * - extensions are just fields, so we build a synthetic message
     *   type with all the (extension) fields.
     * - the field names are created by DescriptorRegistry.getExtensionName(),
     *   which produces for example "spec.option_name", where "spec" is
     *   the package and "option_name" is the field name.
     * - then we concatenate all unknown field data of the option and
     *   read the data with our synthetic message type
     * - the read message is then simply converted to JSON
     *
     * The optional "optionBlacklist" will exclude matching options.
     * The blacklist can contain exact extension names, or use the wildcard
     * character `*` to match a namespace or even all options.
     *
     * Note that options on options (google.protobuf.*Options) are not
     * supported.
