ai.tegmentum.wasmtime4j.panama.util.BacktraceDeserializer
public final class BacktraceDeserializer extends Object
Utility class for deserializing backtrace data from native FFI.

Deserializes binary backtrace format produced by Panama FFI backtrace capture functions. The format matches the serialization in panama_ffi.rs: 

 Backtrace: [frame_count: u32][force_capture: u8][frames...]
 Frame: [func_index: u32][has_func_name: u8][func_name_len: u32][func_name: bytes]
        [has_module_offset: u8][module_offset: u32][has_func_offset: u8][func_offset: u32]
        [has_module_name: u8][module_name_len: u32][module_name: bytes]
        [symbol_count: u32][symbols...]
 Symbol: [has_name: u8][name_len: u32][name: bytes][has_file: u8][file_len: u32][file: bytes]
         [has_line: u8][line: u32][has_column: u8][column: u32]
