hs-deepseq-1.1.0.2p0 – deep evaluation of data structures
Description
This package provides methods for fully evaluating data structures
("deep evaluation"). Deep evaluation is often used for adding
strictness to a program, e.g. in order to force pending exceptions,
remove space leaks, or force lazy I/O to happen. It is also useful
in parallel programs, to ensure pending work does not migrate to
the wrong thread.
The primary use of this package is via the 'deepseq' function, a
"deep" version of 'seq'. It is implemented on top of an 'NFData'
typeclass ("Normal Form Data", data structures with no unevaluated
components) which defines strategies for fully evaluating different
data types.
