Struct tonic_build::Builder

pub struct Builder { /* fields omitted */ }

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 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 format(self, run: bool) -> Self

Enable the output to be formated by rustfmt.

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 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_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 compile<P>(self, protos: &[P], includes: &[P]) -> Result<()> where
    P: AsRef<Path>, 

Compile the .proto files and execute code generation.

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

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