Cargo Features

[dependencies]
tirse = { version = "0.6.0", default-features = false, features = ["use_std"] }
default = byteorder, either, serde

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

use_std

Enables std of byteorder, use_std of either and 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.

byteorder default use_std?
serde default use_std?
either default use_std?
