Cargo Features

[dependencies]
ctfs = { version = "1.0.2", default-features = false, features = ["std", "persistence", "networking"] }

default = std

The std feature is set by default whenever ctfs is added without default-features = false somewhere in the dependency tree.

std default networking? persistence? = libc

Enables std of blake3

blake3:

Enables std::io traits, including impl Write for Hasher, impl Read and Seek for OutputReader, and the Hasher::update_reader method. This feature is enabled by default. (Previously this also controlled runtime CPU feature detection on x86, but now we use the no-std-compatible cpufeatures crate for that.) Also enables the std feature of the constant_time_eq dependency, which toggles a runtime feature check on 64-bit ARM targets.

Affects escrow::pending, algebra::causal_consistency, checkpoint::wal_truncate, checkpoint::CheckpointManager, metrics::prometheus…

persistence = crc32fast, io-uring, std

Affects core::persistence, worker::ZeroCopyNetworkWorker, worker::ZeroCopyNetworkHandle, worker::ZeroCopyBroadcastEntry, worker::ZeroCopyCommand…

networking = crc32fast, std, tokio

Affects metrics::http, ctfs::network…

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
