Service generator builder.

Implementations

impl Builder

pub fn build_client(self, enable: bool) -> Self

Enable or disable gRPC client code generation.

pub fn build_server(self, enable: bool) -> Self

Enable or disable gRPC server code generation.

pub fn build_transport(self, enable: bool) -> Self

Enable or disable generated clients and servers to have built-in tonic transport features.

When the transport feature is disabled this does nothing.

pub fn file_descriptor_set_path(self, path: impl AsRef<Path>) -> Self

Generate a file containing the encoded prost_types::FileDescriptorSet for protocol buffers modules. This is required for implementing gRPC Server Reflection.

pub fn skip_protoc_run(self) -> Self

In combination with with file_descriptor_set_path, this can be used to provide a file descriptor set as an input file, rather than having prost-build generate the file by calling protoc.

pub fn out_dir(self, out_dir: impl AsRef<Path>) -> Self

Set the output directory to generate code to.

Defaults to the OUT_DIR environment variable.

pub fn extern_path( self, proto_path: impl AsRef<str>, rust_path: impl AsRef<str> ) -> Self

Declare externally provided Protobuf package or type.

Passed directly to prost_build::Config.extern_path. Note that both the Protobuf path and the rust package paths should both be fully qualified. i.e. Protobuf paths should start with “.” and rust paths should start with “::”

pub fn field_attribute<P: AsRef<str>, A: AsRef<str>>( self, path: P, attribute: A ) -> Self

Add additional attribute to matched messages, enums, and one-offs.

Passed directly to prost_build::Config.field_attribute.

pub fn type_attribute<P: AsRef<str>, A: AsRef<str>>( self, path: P, attribute: A ) -> Self

Add additional attribute to matched messages, enums, and one-offs.

Passed directly to prost_build::Config.type_attribute.

pub fn message_attribute<P: AsRef<str>, A: AsRef<str>>( self, path: P, attribute: A ) -> Self

Add additional attribute to matched messages.

Passed directly to prost_build::Config.message_attribute.

pub fn enum_attribute<P: AsRef<str>, A: AsRef<str>>( self, path: P, attribute: A ) -> Self

Add additional attribute to matched enums.

Passed directly to prost_build::Config.enum_attribute.

pub fn boxed<P: AsRef<str>>(self, path: P) -> Self

Add additional boxed fields.

Passed directly to prost_build::Config.boxed.

pub fn btree_map<I, S>(self, paths: I) -> Self

where I: IntoIterator<Item = S>, S: AsRef<str>,

Configure the code generator to generate Rust BTreeMap fields for Protobuf map type fields.

Passed directly to prost_build::Config.btree_map.

Note: previous configurated paths for btree_map will be cleared.

pub fn bytes<I, S>(self, paths: I) -> Self

where I: IntoIterator<Item = S>, S: AsRef<str>,

Configure the code generator to generate Rust bytes::Bytes fields for Protobuf bytes type fields.

Passed directly to prost_build::Config.bytes.

Note: previous configurated paths for bytes will be cleared.

pub fn server_mod_attribute<P: AsRef<str>, A: AsRef<str>>( self, path: P, attribute: A ) -> Self

Add additional attribute to matched server mods. Matches on the package name.

pub fn server_attribute<P: AsRef<str>, A: AsRef<str>>( self, path: P, attribute: A ) -> Self

Add additional attribute to matched service servers. Matches on the service name.

pub fn client_mod_attribute<P: AsRef<str>, A: AsRef<str>>( self, path: P, attribute: A ) -> Self

Add additional attribute to matched client mods. Matches on the package name.

pub fn client_attribute<P: AsRef<str>, A: AsRef<str>>( self, path: P, attribute: A ) -> Self

Add additional attribute to matched service clients. Matches on the service name.

pub fn proto_path(self, proto_path: impl AsRef<str>) -> Self

Set the path to where tonic will search for the Request/Response proto structs live relative to the module where you call include_proto!.

This defaults to super since tonic will generate code in a module.

pub fn protoc_arg<A: AsRef<str>>(self, arg: A) -> Self

Configure Prost protoc_args build arguments.

Note: Enabling --experimental_allow_proto3_optional requires protobuf >= 3.12.

pub fn disable_comments(self, path: impl AsRef<str>) -> Self

Disable service and rpc comments emission.

pub fn use_arc_self(self, enable: bool) -> Self

Emit Arc<Self> receiver type in server traits instead of &self.

pub fn disable_package_emission(self) -> Self

Emits GRPC endpoints with no attached package. Effectively ignores protofile package declaration from grpc context.

This effectively sets prost’s exported package to an empty string.

pub fn compile_well_known_types(self, compile_well_known_types: bool) -> Self

Enable or disable directing Prost to compile well-known protobuf types instead of using the already-compiled versions available in the prost-types crate.

This defaults to false.

pub fn include_file(self, path: impl AsRef<Path>) -> Self

Configures the optional module filename for easy inclusion of all generated Rust files

If set, generates a file (inside the OUT_DIR or out_dir() as appropriate) which contains a set of pub mod XXX statements combining to load all Rust files generated. This can allow for a shortcut where multiple related proto files have been compiled together resulting in a semi-complex set of includes.

pub fn emit_rerun_if_changed(self, enable: bool) -> Self

Enable or disable emitting cargo:rerun-if-changed=PATH instructions for Cargo.

If set, writes instructions to stdout for Cargo so that it understands when to rerun the build script. By default, this setting is enabled if the CARGO environment variable is set. The CARGO environment variable is set by Cargo for build scripts. Therefore, this setting should be enabled automatically when run from a build script. However, the method of detection is not completely reliable since the CARGO environment variable can have been set by anything else. If writing the instructions to stdout is undesireable, you can disable this setting explicitly.

pub fn generate_default_stubs(self, enable: bool) -> Self

Enable or disable directing service generation to providing a default implementation for service methods. When this is false all gRPC methods must be explicitly implemented. When this is true any unimplemented service methods will return ‘unimplemented’ gRPC error code. When this is true all streaming server request RPC types explicitly use tonic::codegen::BoxStream type.

This defaults to false.

pub fn compile( self, protos: &[impl AsRef<Path>], includes: &[impl AsRef<Path>] ) -> Result<()>

Compile the .proto files and execute code generation.

pub fn compile_with_config( self, config: Config, protos: &[impl AsRef<Path>], includes: &[impl AsRef<Path>] ) -> Result<()>

Compile the .proto files and execute code generation using a custom prost_build::Config.

pub fn service_generator(self) -> Box<dyn ServiceGenerator>

Turn the builder into a ServiceGenerator ready to be passed to prost-builds Config::service_generator.
