.SS "Package Selection"
|
|
By default, when no package selection options are given, the packages selected
|
|
depend on the selected manifest file (based on the current working directory if
|
|
\fB\-\-manifest\-path\fR is not given). If the manifest is the root of a workspace then
|
|
the workspaces default members are selected, otherwise only the package defined
|
|
by the manifest will be selected.
|
|
.sp
|
|
The default members of a workspace can be set explicitly with the
|
|
\fBworkspace.default\-members\fR key in the root manifest. If this is not set, a
|
|
virtual workspace will include all workspace members (equivalent to passing
|
|
\fB\-\-workspace\fR), and a non\-virtual workspace will include only the root crate itself.
