Struct ObjectTransformLayerRef 

pub struct ObjectTransformLayerRef {
    ptr: LLVMOrcObjectTransformLayerRef,
}

A reference to an object transform layer.

The transform layer sits between the IR compiler and the object linking layer. A transform callback can inspect or modify the compiled object buffer before linking.

Fields

ptr: LLVMOrcObjectTransformLayerRef

Implementations

impl ObjectTransformLayerRef

pub unsafe fn from_inner(ptr: LLVMOrcObjectTransformLayerRef) -> Self

Wraps a raw pointer.

pub fn as_inner(&self) -> LLVMOrcObjectTransformLayerRef

Unwraps the raw pointer.

pub fn set_transform(&self, f: fn(&[u8]) -> Result<Option<Vec<u8>>, String>)

Set the transform function on this object transform layer.

The callback receives the compiled object buffer as &[u8]. Returning Ok(None) passes the buffer through unchanged; returning Ok(Some(new_bytes)) replaces it. Returning Err aborts materialization.

pub unsafe fn set_transform_raw( &self, f: extern "C" fn(ctx: *mut c_void, obj_in_out: *mut LLVMMemoryBufferRef) -> LLVMErrorRef, ctx: *mut c_void, )

Set a raw transform function on this object transform layer.

Safety

ctx must be valid for the lifetime of this layer and f must not unwind.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
