Function resolve_ws_with_opts 

pub fn resolve_ws_with_opts<'gctx>(
    ws: &Workspace<'gctx>,
    target_data: &mut RustcTargetData<'gctx>,
    requested_targets: &[CompileKind],
    cli_features: &CliFeatures,
    specs: &[PackageIdSpec],
    has_dev_units: HasDevUnits,
    force_all_targets: ForceAllTargets,
    dry_run: bool,
) -> CargoResult<WorkspaceResolve<'gctx>>

Resolves dependencies for some packages of the workspace, taking into account paths overrides and activated features.

This function will also write the result of resolution as a new lock file (unless Workspace::require_optional_deps is false, such as cargo install or -Z avoid-dev-deps), or it is an ephemeral workspace (cargo install or cargo package).

specs may be empty, which indicates it should resolve all workspace members. In this case, opts.all_features must be true.
