Cargo Features

TypeIdSuffix has no features set by default.

[dependencies]
typeid_suffix = { version = "1.0.2-beta.1", features = ["instrument"] }
instrument = tracing

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.
