API to generate .rs
files to be used e. g. from build.rs.
Example code:
use ttrpc_codegen::Codegen;
use ttrpc_codegen::Customize;
fn main() {
Codegen::new()
.out_dir("protocols/sync")
.inputs(&protos)
.include("protocols/protos")
.rust_protobuf()
.customize(Customize {
..Default::default()
})
.run()
.expect("Gen code failed.");
}
And in Cargo.toml
:
[build-dependencies]
ttrpc-codegen = "0.3"
The alternative is to use
protoc-rust crate,
which relies on protoc
command to parse descriptors. Both crates should produce the same result,
otherwise please file a bug report.
