Rust SDK for Google Trillian

Intends to provide current (!) rust sources for Trillian's protobufs.

Trillian's protos are themselves dependent on Google APIs and so this crate takes a dependency on rust-googleapis

The crate clones Trillian and Google APIs which contains Google's public interface definitions (including protos).

The result is a crate called rust-trillian that includes a google module that includes the various Trillian modules:

• trillian
• trillian_admin_api
• trillian_admin_api_grpc
• trillian_log_api
• trillian_log_api_grpc
• trillian_log_sequencer_api
• trillian_log_sequencer_api_grpc
• trillian_map_api
• trillian_map_api_grpc

and their dependents:

• keyspb
• sigpb

NB The google module may be redundant

Structure

Trillian's protos are split across multiple files to partition by functionality, e.g. Trillian Log, Trillian Map. With Golang, Java and others, it's possible to publish these (different files) into a singular namespace. With Rust, different files denotes different modules and so the Rust module structure includes an additional layer that's not present in the other languages.
