Cargo Features

[dependencies]
rust-fontconfig = { version = "0.1.13", default-features = false, features = ["std", "multithreading", "parsing"] }
default = multithreading, parsing, std

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

std default = mmapio
multithreading default = rayon
parsing default = allsorts

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.

rayon multithreading
allsorts parsing
mmapio not wasm std
