pub struct ExtrasSpecificationWithDefaults { /* private fields */ }Expand description
A trivial newtype wrapped around ExtrasSpecification that signifies “defaults applied”
It includes a copy of the previous semantics to provide info on if the group being a default actually affected it being enabled, because it’s obviously “correct”. (These are Arcs so it’s ~free to hold onto the previous semantics)
Implementations§
Source§impl ExtrasSpecificationWithDefaults
impl ExtrasSpecificationWithDefaults
Sourcepub fn none() -> Self
pub fn none() -> Self
Do not enable any extras
Many places in the code need to know what extras are active, but various commands or subsystems never enable any extras, in which case they want this.
Sourcepub fn contains_because_default(&self, extra: &ExtraName) -> bool
pub fn contains_because_default(&self, extra: &ExtraName) -> bool
Returns true if the specification was enabled, and only because it was a default
Methods from Deref<Target = ExtrasSpecification>§
Sourcepub fn with_defaults(
&self,
defaults: DefaultExtras,
) -> ExtrasSpecificationWithDefaults
pub fn with_defaults( &self, defaults: DefaultExtras, ) -> ExtrasSpecificationWithDefaults
Apply defaults to a base ExtrasSpecification.
Methods from Deref<Target = ExtrasSpecificationInner>§
Sourcepub fn prod(&self) -> bool
pub fn prod(&self) -> bool
Returns true if packages other than the ones referenced by these
extras should be considered.
That is, if I tell you to install a project and this is false, you should ignore the project itself and all its dependencies, and instead just install the extras.
(This is really just asking if an –only flag was passed.)
Sourcepub fn contains(&self, extra: &ExtraName) -> bool
pub fn contains(&self, extra: &ExtraName) -> bool
Returns true if the specification includes the given extra.
Sourcepub fn desugarred_names(&self) -> impl Iterator<Item = &ExtraName>
pub fn desugarred_names(&self) -> impl Iterator<Item = &ExtraName>
Iterate over all extras that we think should exist.
Sourcepub fn extra_names<'a, Names>(
&'a self,
all_names: Names,
) -> impl Iterator<Item = &'a ExtraName> + 'a
pub fn extra_names<'a, Names>( &'a self, all_names: Names, ) -> impl Iterator<Item = &'a ExtraName> + 'a
Returns an iterator over all extras that are included in the specification,
assuming all_names is an iterator over all extras.
Sourcepub fn explicit_names(&self) -> impl Iterator<Item = &ExtraName>
pub fn explicit_names(&self) -> impl Iterator<Item = &ExtraName>
Iterate over all groups the user explicitly asked for on the CLI
Sourcepub fn history(&self) -> &ExtrasSpecificationHistory
pub fn history(&self) -> &ExtrasSpecificationHistory
Get the raw history for diagnostics
