  • Rust Issue #: (leave this empty)

Summary

Values should be able to be passed as type parameters. The [T, ..n] fixed length array should be changed to use a value as a type parameter.

  • Rust Issue #: (leave this empty)

Summary

This adds the ability to refer to fields of types and use them later on with objects of that type. The FieldOffset<Obj, Field> type is added which refers to fields of type Field in the object Obj. The offsetof Type.field syntax is defined to construct instances of FieldOffset<Type, the type of field>.

All code is shared between processes. Processes can not read or write to the code segment.
The global code segment is 2 TB. It is split into 1MB blocks, giving 2M blocks in total.
A module is a executable or shared library.
Each process has an bitmap where each bit represents a block of code of the code segment.
With 1 bit per block means the size of the array is 256KB.
If a bit is 0, the process does not have access to the block in the code segment.
