Fields

compiler: Option<Box<dyn Compiler>>

The compiler and cpu features

features: Features

The compiler and cpu features

code_memory: Vec<CodeMemory>

The code memory is responsible of publishing the compiled functions to memory.

signatures: SignatureRegistry

The signature registry is used mainly to operate with trampolines performantly.
