# 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`. `LinkedComponent`s 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`.
