Compilation configuration for one crate.
Reading a configset, adding an entry to it, then writing it back.
let mut configuration = PackageConfig::read(&config_file).unwrap();
configuration.insert("cargo_update".to_string(), PackageConfig::from(&operations));
PackageConfig::write(&configuration, &config_file).unwrap();
Toolchain to use to compile the package, or None
for default.
Whether to compile the package with the default features.
Features to compile the package with.
Whether to compile in debug mode.
Whether to compile in debug mode.
Create a package config based on the default settings and modified according to the specified operations.

Generate cargo arguments from this configuration.

Read a configset from the specified file.
If the specified file doesn't exist an empty configset is returned.

Save a configset to the specified file.
