Documentation

data LinkedComponent Source #

A linked component is a component that has been mix-in linked, at which point we have determined how all the dependencies of the component are explicitly instantiated (in the form of an OpenUnitId). ConfiguredComponent is mix-in linked into LinkedComponent, which is then instantiated into ReadyComponent.

Fields

lc_ann_id :: AnnotatedId ComponentId
Uniquely identifies linked component
lc_component :: Component
Corresponds to cc_component.
lc_exe_deps :: [AnnotatedId OpenUnitId]
build-tools and build-tool-depends dependencies. Corresponds to cc_exe_deps.
lc_public :: Bool
Is this the public library of a package? Corresponds to cc_public.
lc_includes :: [ComponentInclude OpenUnitId ModuleRenaming]
Corresponds to cc_includes, but (1) this does not contain includes of signature packages (packages with no exports), and (2) the ModuleRenaming for requirements (stored in IncludeRenaming) has been removed, as it is reflected in OpenUnitId.)
lc_sig_includes :: [ComponentInclude OpenUnitId ModuleRenaming]
Like lc_includes, but this specifies includes on signature packages which have no exports.
lc_shape :: ModuleShape
The module shape computed by mix-in linking. This is newly computed from ConfiguredComponent

Instances

Instances details

Package LinkedComponent Source #
Instance details Defined in Distribution.Backpack.LinkedComponent Methods packageId :: LinkedComponent -> PackageIdentifier Source #

lc_insts :: LinkedComponent -> [(ModuleName, OpenModule)] Source #

The instantiation of lc_uid; this always has the invariant that it is a mapping from a module name A to A (the hole A).

lc_uid :: LinkedComponent -> OpenUnitId Source #

The OpenUnitId of this component in the "default" instantiation. See also lc_insts. LinkedComponents cannot be instantiated (e.g., there is no ModSubst instance for them).

lc_cid :: LinkedComponent -> ComponentId Source #

Uniquely identifies a LinkedComponent. Corresponds to cc_cid.

lc_pkgid :: LinkedComponent -> PackageId Source #

Corresponds to cc_pkgid.

toLinkedComponent Source #

Arguments

:: Verbosity
-> Bool	Whether there are any "promised" package dependencies which we won't find already installed.

toLinkedComponents Source #

Arguments

:: Verbosity
-> Bool	Whether there are any "promised" package dependencies which we won't find already installed.

dispLinkedComponent :: LinkedComponent -> Doc Source #
