common

mc-common

This crate contains several things right now:

• Common structs that are used at API boundaries of higher-level crates. Putting the structs in common instead of in a larger crate allows us to break up dependencies, and minimize the amount of code that compiles as std and no_std.
• Common error types, used at API boundaries. The rationale is similar.
• A hashmap object based on hashbrown that works in and out of the enclave.
• A simple LRU cache implementation
• Logging functionality. Some of this is enclave compatible, some isn't, this is controlled by log and loggers features.

Note (enclave logging)

The mc-sgx-slog crate provides an slog::Logger appropriate for the enclave. It is recommended to refer to mc_common::logger::Logger in the portable enclave-impl crates, and put the calls to mc-sgx-slog in the enclave-trusted crates.
