Cargo Features

[dependencies]
tbf = { version = "0.1.7", default-features = false, features = ["std", "imfs", "dfs", "serde"] }
default = dfs, imfs, std

These default features are set whenever tbf is added without default-features = false somewhere in the dependency tree.

std default dfs
imfs default = spin

Builtin implementations of the protocol

dfs default = std

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.

spin imfs
serde implicit feature

Enables serde

serde:

A generic serialization/deserialization framework
