Struct DependencyGroups 

pub struct DependencyGroups(/* private fields */);

Manager of all dependency-group decisions and settings history.

This is an Arc mostly just to avoid size bloat on things that contain these.

Implementations

impl DependencyGroups

pub fn from_args( dev: bool, no_dev: bool, only_dev: bool, group: Vec<GroupName>, no_group: Vec<GroupName>, no_default_groups: bool, only_group: Vec<GroupName>, all_groups: bool, ) -> Self

Create from raw CLI args

pub fn from_dev_mode(dev_mode: DevMode) -> Self

Helper to make a spec from just a –dev flag

pub fn from_group(group: GroupName) -> Self

Helper to make a spec from just a –group

pub fn with_defaults( &self, defaults: DefaultGroups, ) -> DependencyGroupsWithDefaults

Apply defaults to a base DependencyGroups.

This is appropriate in projects, where the dev group is synced by default.

Methods from Deref<Target = DependencyGroupsInner>

pub fn prod(&self) -> bool

Returns true if packages other than the ones referenced by these dependency-groups 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 dependency-groups.

(This is really just asking if an –only flag was passed.)

pub fn contains(&self, group: &GroupName) -> bool

Returns true if the specification includes the given group.

pub fn desugarred_names(&self) -> impl Iterator<Item = &GroupName>

Iterate over all groups that we think should exist.

pub fn group_names<'a, Names>( &'a self, all_names: Names, ) -> impl Iterator<Item = &'a GroupName> + 'a

where Names: Iterator<Item = &'a GroupName> + 'a,

Returns an iterator over all groups that are included in the specification, assuming all_names is an iterator over all groups.

pub fn explicit_names(&self) -> impl Iterator<Item = &GroupName>

Iterate over all groups the user explicitly asked for on the CLI

pub fn is_empty(&self) -> bool

Returns true if the specification will have no effect.

pub fn history(&self) -> &DependencyGroupsHistory

Get the raw history for diagnostics

Performs copy-assignment from source.

impl Debug for DependencyGroups

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DependencyGroups

fn default() -> DependencyGroups

Returns the “default value” for a type.
