Implementations

impl Crates

pub fn from(path: &Path) -> Result<Crates>

Deserialize from a ~/.cargo/.crates2.json file and process each crate in parallel to:

• Parse the name, version, source, rust version
• Get the latest avaiable version
• Determine the crate type

Errors

Returns an error if not able to read the file at the given path

pub fn is_empty(&self) -> bool

Return true if no crates are installed

pub fn crates(&self) -> BTreeMap<&str, &Crate>

Return a view of all crates

pub fn from_include(path: &Path, patterns: &[&str]) -> Result<Crates>

Like the Crates::from method, but accepts zero or more include patterns to match against crate names

Errors

Returns an error if not able to read the file at the given path or a pattern is not a valid regular expression
