Implementations§

source§

impl Version

source

pub fn name(&self) -> &str

Name of the crate

source

pub fn version(&self) -> &str

Name of this version

source

pub fn dependencies(&self) -> &[Dependency]

Dependencies for this version

source

pub fn checksum(&self) -> &[u8; 32]

Checksum of the package for this version

SHA256 of the .crate file

source

pub fn features(&self) -> &HashMap<String, Vec<String>>

Explicit features this crate has. This list is not exhaustive, because any optional dependency becomes a feature automatically.

default is a special feature name for implicitly enabled features.

Exclusivity flag. If this is a sys crate, it informs it conflicts with any other crate with the same links string.

It does not involve linker or libraries in any way.

source

pub fn is_yanked(&self) -> bool

Whether this version was yanked from the index

source

pub fn rust_version(&self) -> Option<&str>

Required version of rust

Corresponds to package.rust-version.

Added in 2023 (see https://github.com/rust-lang/crates.io/pull/6267), can be None if published before then or if not set in the manifest.

source

pub fn download_url(&self, index: &IndexConfig) -> Option<String>

Where to find crate tarball
