Distribution.Types.AbiDependency

Synopsis

data AbiDependency = AbiDependency {
- depUnitId :: UnitId
- depAbiHash :: AbiHash
}

Documentation

data AbiDependency Source #

An ABI dependency is a dependency on a library which also records the ABI hash (abiHash) of the library it depends on.

The primary utility of this is to enable an extra sanity when GHC loads libraries: it can check if the dependency has a matching ABI and if not, refuse to load this library. This information is critical if we are shadowing libraries; differences in the ABI hash let us know what packages get shadowed by the new version of a package.
