Struct Builder

pub struct Builder { /* private fields */ }

Implementations

impl Builder

pub fn new() -> Self

Create a new Builder

pub fn out_dir<P>(&mut self, path: P) -> &mut Self

where P: Into<PathBuf>,

Configures the output directory where generated Rust files will be written.

If unset, defaults to the OUT_DIR environment variable. OUT_DIR is set by Cargo when executing build scripts, so out_dir typically does not need to be configured.

pub fn register_descriptors(&mut self, descriptors: &[u8]) -> Result<&mut Self>

Register an encoded FileDescriptorSet with this Builder

pub fn exclude<S: Into<String>, I: IntoIterator<Item = S>>( &mut self, prefixes: I, ) -> &mut Self

Don’t generate code for the following type prefixes

pub fn retain_enum_prefix(&mut self) -> &mut Self

Configures the code generator to not strip the enum name from variant names.

pub fn extern_path( &mut self, proto_path: impl Into<String>, rust_path: impl Into<String>, ) -> &mut Self

Declare an externally provided Protobuf package or type

pub fn build<S: AsRef<str>>(&mut self, prefixes: &[S]) -> Result<()>

Generates code for all registered types where prefixes contains a prefix of the fully-qualified path of the type

Trait Implementations

impl Debug for Builder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Builder

fn default() -> Builder

Returns the “default value” for a type.
