Macro tonic::include_file_descriptor_set [−][src]
Include an encoded prost_types::FileDescriptorSet
as a &'static [u8]
. The parameter must be
the stem of the filename passed to file_descriptor_set_path
for the tonic-build::Builder
,
excluding the .bin
extension.
For example, a file descriptor set compiled like this in build.rs
:
ⓘ
let descriptor_path = PathBuf::from(env::var("OUT_DIR").unwrap()).join("my_descriptor.bin") tonic_build::configure() .file_descriptor_set_path(&descriptor_path) .format(true) .compile(&["proto/reflection.proto"], &["proto/"])?;
Can be included like this:
ⓘ
mod pb { pub(crate) const FILE_DESCRIPTOR_SET: &[u8] = tonic::include_file_descriptor_set!("my_descriptor"); }
Note:
This only works if the tonic-build output directory has been unmodified.
The default output directory is set to the [OUT_DIR
] environment variable.
If the output directory has been modified, the following pattern may be used
instead of this macro.
ⓘ
mod pb { pub(crate) const FILE_DESCRIPTOR_SET: &[u8] = include_bytes!("/relative/protobuf/directory/descriptor_name.bin"); }
