Struct mesh_protobuf::protofile::DescriptorWriter

pub struct DescriptorWriter<'a> { /* private fields */ }

A type used to write protobuf descriptors to .proto-format files.

Implementations

impl<'a> DescriptorWriter<'a>

pub fn new( descriptors: impl IntoIterator<Item = &'a MessageDescription<'a>>, ) -> Self

Returns a new object for writing the .proto files described by descriptors.

descriptors only needs to contain the roots of the protobuf message graph; any other message types referred to by the types in descriptors will be found and written to .proto files as well.

pub fn file_heading(&mut self, file_heading: &'a str) -> &mut Self

Sets the file heading written to each file.

pub fn write<W: Write>(&self, f: impl FnMut(&str) -> Result<W>) -> Result<()>

Writes the .proto files to writers returned by f.

pub fn write_to_path(&self, path: impl AsRef<Path>) -> Result<Vec<PathBuf>>

Writes the .proto files to disk, rooted at path.

Returns the paths of written files.
