TypedMemory Java library maps records to off-heap native memory using the Foreign Function and Memory API

TypedMemory is a Java 25+ library that provides strongly typed views over contiguous off-heap memory. It lets developers map Java records onto native memory while retaining control over allocation, layout, lifetime, and bulk operations for use cases like interop, graphics, simulation, and data-oriented programming.

The project reflects growing interest in making off-heap memory safer and more ergonomic as Java expands its systems-programming capabilities. By building on the FFM API rather than hiding it, TypedMemory could appeal to developers who need native-level performance without abandoning Java’s type model.
