Function visit_frames

crates/unwinder/src/stackwalk.rs:324–337

Walk through a contiguous sequence of Wasm frames starting with the frame at the given PC and FP and ending at `trampoline_fp`. This FP should correspond to that of a trampoline that was used to enter the Wasm code. We require that the initial PC, FP, and `trampoline_fp` values are non-null (non-zero). # Safety This function is not safe as `unwind`, `pc`, `fp`, and `trampoline_fp` must all be "
