Cargo Features

[dependencies]
probably = { version = "0.3.1", default-features = false, features = ["std", "with_serde", "farmhash"] }
default = std

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

std default = bytecount, rand, siphasher
with_serde = serde_bytes, serde_json

Enables std of serde

serde:

Provide impls for common standard library types like Vec<T> and HashMap<K, V>.
Requires a dependency on the Rust standard library.

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.

bytecount std
rand std

Enables rand ^0.7

siphasher std

Enables siphasher ^0.3

serde_json with_serde?
