Cargo Features

mech-syntax has no features set by default.

[dependencies]
mech-syntax = { version = "0.2.18", features = ["no-std"] }
no-std = rlibc

Enables no-std of mech-core

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.
