Struct Requirement 

pub struct Requirement {
    pub features: Vec<FeatureName>,
    pub default_features: bool,
    pub optional: bool,
    pub source: Option<Source>,
}

A profile another builds on, keyed by its name in [requires].

In the requirer’s own source unless it names another by git.

Fields

features: Vec<FeatureName>

default_features: bool

Whether its default features are on; unless a requirer or the target turns them on.

optional: bool

Whether it applies only when a feature activates it, with dep: or name/feature.

source: Option<Source>

Another source it comes from; None for the requirer’s own.
