Struct RawCallableJitFunction 

pub struct RawCallableJitFunction { /* private fields */ }

A raw JIT-compiled function for manual type conversion

This is a type-erased version of CallableJitFunction that allows manual function pointer conversion for cases not covered by the predefined call() methods.

Usage

let raw_func = RawCallableJitFunction::new(code)?;
 
// Manual conversion to any function type
let func: extern "C" fn(u64, u64, u64, u64, u64, u64, u64, u64) -> u64 = 
    unsafe { raw_func.as_fn() };
let result = func(1, 2, 3, 4, 5, 6, 7, 8);

Implementations

impl RawCallableJitFunction

pub fn new(code: &[u8]) -> Result<Self, JitError>

Create a new raw callable JIT function from instruction bytes

pub unsafe fn as_fn<F>(&self) -> F

Convert to a function pointer of the specified type

Safety

The caller must ensure that:

• The function signature F matches the actual assembled code
• The assembled code follows the expected calling convention (usually C ABI)
• The function pointer is called with valid arguments

Example

let raw_func = RawCallableJitFunction::new(code)?;
 
// For complex signatures not covered by CallableJitFunction
let func: extern "C" fn(u64, u64, u64, u64, u64, u64, u64, u64) -> u64 = 
    unsafe { raw_func.as_fn() };
let result = func(1, 2, 3, 4, 5, 6, 7, 8);
