data ComponentId #

A `ComponentId` uniquely identifies the transitive source code closure of a component (i.e. libraries, executables).

For non-Backpack components, this corresponds one to one with the `UnitId`, which serves as the basis for install paths, linker symbols, etc.

Use `mkComponentId` and `unComponentId` to convert from/to a `String`.

This type is opaque since `Cabal-2.0`

Since: 2.0.0.2

unComponentId :: ComponentId -> String #

Convert `ComponentId` to `String`

Since: 2.0.0.2

mkComponentId :: String -> ComponentId #

Construct a `ComponentId` from a `String`

`mkComponentId` is the inverse to `unComponentId`

Note: No validations are performed to ensure that the resulting `ComponentId` is valid
