Method loaded_code_by_pc

crates/wasmtime/src/runtime/module/registry.rs:159–166

Looks up `pc`, an absolute program counter address, to see if it corresponds to any loaded code within this [`ModuleRegistry`]. Returns `None` if nothing is found, and otherwise returns the corresponding [`LoadedCode`] as well as a relative pc from the start of the code's text section if found.

    /// the code's text section if found.

        let (_, code) = self
            .loaded_code

            .next_back()?;
        let offset = StoreCodePC::offset_of(code.code.text_range(), pc)?;
        Some((code, offset))
    }
