Inko's virtual machine ("IVM" for short) is a register based, bytecode virtual machine, written in Rust. IVM uses preemptive multitasking for executing processes, and manages memory using a garbage collector and allocator based on Immix.
The bytecode executed by the VM is reasonably compact, although it could probably be optimised a bit more.
IVM uses prototype-based objects internally, although this is mostly hidden from the language.
IVM can be compiled using musl, allowing you to easily distribute the executable across different versions of the same operating system.
The executable is reasonably small: around 4.2 MB when using musl without stripping debugging symbols, and roughly 1.1 MB after stripping debugging symbols.
Currently there is no JIT, though we hope to implement one some time in the future.
