Elfo is another actor system. Check The Actoromicon.
Note: although it's already actively used in production, it's still under development. Wait for v0.2 for public announcement.
To use elfo, add this to your Cargo.toml:
[dependencies]
elfo = { version = "0.2.0-alpha.8", features = ["full"] }
[dev-dependencies]
elfo = { version = "0.2.0-alpha.8", features = ["test-util"] }Note: until sharded-slab#80 is merged, it should be added:
[patch.crates-io]
sharded-slab = { git = 'https://github.com/loyd/sharded-slab.git' }
