Struct PackageLink

source 
pub struct PackageLink<'g> { /* private fields */ }
Expand description

Represents a dependency from one package to another.

This struct contains information about:

  • whether this dependency was renamed in the context of this crate.
  • if this is a normal, dev and/or build dependency.
  • platform-specific information about required, optional and status

Implementations§

source§

impl<'g> PackageLink<'g>

source

pub fn from(&self) -> PackageMetadata<'g>

Returns the package which depends on the to package.

source

pub fn to(&self) -> PackageMetadata<'g>

Returns the package which is depended on by the from package.

source

pub fn endpoints(&self) -> (PackageMetadata<'g>, PackageMetadata<'g>)

Returns the endpoints as a pair of packages (from, to).

source

pub fn dep_name(&self) -> &'g str

Returns the name for this dependency edge. This can be affected by a crate rename.

source

pub fn resolved_name(&self) -> &'g str

Returns the resolved name for this dependency edge. This may involve renaming the crate and replacing - with _.

source

pub fn version_req(&self) -> &'g VersionReq

Returns the semver requirements specified for this dependency.

To get the resolved version, see the to field of the PackageLink this was part of.

§Notes

A dependency can be requested multiple times, possibly with different version requirements, even if they all end up resolving to the same version. version_req will return any of those requirements.

See Specifying Dependencies in the Cargo reference for more details.

source

pub fn normal(&self) -> DependencyReq<'g>

Returns details about this dependency from the [dependencies] section.

source

pub fn build(&self) -> DependencyReq<'g>

Returns details about this dependency from the [build-dependencies] section.

source

pub fn dev(&self) -> DependencyReq<'g>

Returns details about this dependency from the [dev-dependencies] section.

source

pub fn req_for_kind(&self, kind: DependencyKind) -> DependencyReq<'g>

Returns details about this dependency from the section specified by the given dependency kind.

source

pub fn dev_only(&self) -> bool

Return true if this edge is dev-only, i.e. code from this edge will not be included in normal builds.
