Implementations

impl Crate

pub fn new<P: AsRef<Path>>(index_path: P) -> Result<Crate>

Parse the file with crate versions.

The file must contain at least one version.

pub fn from_slice(bytes: &[u8]) -> Result<Crate>

Parse crate file from in-memory JSON data

pub fn from_cache_slice(bytes: &[u8], index_version: &str) -> Result<Crate>

Parse crate index entry from a .cache file, this can fail for a number of reasons

1. There is no entry for this crate
2. The entry was created with an older commit and might be outdated
3. The entry is a newer version than what can be read, would only happen if a future version of cargo changed the format of the cache entries
4. The cache entry is malformed somehow

pub fn versions(&self) -> &[Version]

Published versions of this crate sorted chronologically by date published

pub fn earliest_version(&self) -> &Version

Oldest version.

Warning: may not be the lowest version number.

pub fn latest_version(&self) -> &Version

Most recently published version. Warning: may not be the highest version.

pub fn highest_version(&self) -> SemverVersion
