Cargo Features

[dependencies]
ioslice = { version = "0.6.0", default-features = false, features = ["std", "alloc", "io_box", "nightly", "stable_deref_trait"] }
default = io_box, std

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

std default = alloc, libc, winapi
alloc io_box std
io_box default = alloc
nightly

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.

stable_deref_trait implicit feature
libc unix std
winapi win std
