Struct protobuf_codegen::Codegen [−][src]
pub struct Codegen { /* fields omitted */ }
Expand description
Protoc --rust_out...
args
Implementations
Create new codegen object.
Uses protoc
from $PATH
by default.
Can be switched to pure rust parser using pure
function.
Output directory for generated code.
Add include directories.
Append a .proto
file path to compile
Append multiple .proto
file paths to compile
Specify protoc
command path to be used when invoking code generation.
Examples
use protobuf_codegen::Codegen;
Codegen::new()
.protoc()
.protoc_path(protoc_bin_vendored::protoc_bin_path().unwrap())
// ...
.run()
.unwrap();
This option is ignored when pure Rust parser is used.
Set options to customize code generation
Extra command line flags for protoc
invocation.
For example, --experimental_allow_proto3_optional
option.
This option is ignored when pure Rust parser is used.
Invoke the code generation.
This is roughly equivalent to protoc --rust_out=...
but
without requiring protoc-gen-rust
command in $PATH
.
This function uses pure Rust parser or protoc
parser depending on
how this object was configured.
Similar to run
, but prints the message to stderr and exits the process on error.
