Struct guppy::graph::DependencyReq
source · [−]pub struct DependencyReq<'g> { /* private fields */ }Expand description
Information about a specific kind of dependency (normal, build or dev) from a package to another package.
Usually found within the context of a PackageLink.
Implementations
sourceimpl<'g> DependencyReq<'g>
impl<'g> DependencyReq<'g>
sourcepub fn is_present(&self) -> bool
pub fn is_present(&self) -> bool
Returns true if there is at least one Cargo.toml entry corresponding to this requirement.
For example, if this dependency is specified in the [dev-dependencies] section,
edge.dev().is_present() will return true.
sourcepub fn status(&self) -> EnabledStatus<'g>
pub fn status(&self) -> EnabledStatus<'g>
Returns the enabled status of this dependency.
status is the union of default_features and no_default_features.
See the documentation for EnabledStatus for more.
sourcepub fn default_features(&self) -> EnabledStatus<'g>
pub fn default_features(&self) -> EnabledStatus<'g>
Returns the enabled status of this dependency when default-features = true.
See the documentation for EnabledStatus for more.
sourcepub fn no_default_features(&self) -> EnabledStatus<'g>
pub fn no_default_features(&self) -> EnabledStatus<'g>
Returns the enabled status of this dependency when default-features = false.
This is generally less useful than status or default_features, but is provided for
completeness.
See the documentation for EnabledStatus for more.
sourcepub fn features(&self) -> impl Iterator<Item = &'g str>
pub fn features(&self) -> impl Iterator<Item = &'g str>
Returns a list of all features possibly enabled by this dependency. This includes features that are only turned on if the dependency is optional, or features enabled by inactive platforms.
sourcepub fn feature_status(&self, feature: &str) -> EnabledStatus<'g>
pub fn feature_status(&self, feature: &str) -> EnabledStatus<'g>
Returns the enabled status of this feature.
Note that as of Rust 1.42, the default feature resolver behaves in potentially surprising ways. See the Cargo reference for more.
See the documentation for EnabledStatus for more.
