Cargo Features

[dependencies]
gadget-std = { version = "0.1.0", default-features = false, features = ["std", "tokio", "parallel", "print-trace", "getrandom"] }

default = std

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

std default parallel? print-trace? = getrandom

Enables std of thiserror

thiserror:

Std feature enables support for formatting std::path::{Path, PathBuf}
conveniently in an error message.

#[derive(Error, Debug)]
#[error("failed to create configuration file {path}")]
pub struct MyError {
pub path: PathBuf,
pub source: std::io::Error,
}

Without std, this would need to be written #[error("... {}", path.display())].

tokio

Enables async-trait and tokio

Affects gadget-std::tokio_ext…

parallel = rayon, std

print-trace = std

Affects perf_trace::inner…

getrandom std

Enables std of rand ^0.8.5

rand:

Option (enabled by default): without "std" rand uses libcore; this option enables functionality expected to be available on a standard platform.

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.
