Metadata associated with a compiled ELF artifact.

Fields

native_debug_info_present: bool

Whether or not native debug information is available in obj

has_unparsed_debuginfo: bool

Whether or not the original wasm module contained debug information that we skipped and did not parse.

code_section_offset: u64

Offset in the original wasm file to the code section.

has_wasm_debuginfo: bool

Whether or not custom wasm-specific dwarf sections were inserted into the ELF image.

Note that even if this flag is true sections may be missing if they weren’t found in the original wasm module itself.

is_pulley: bool

Whether this artifact contains Pulley bytecode (instead of machine code) or not.

dwarf: Vec<(u8, Range<u64>)>

Dwarf sections and the offsets at which they’re stored in the ELF_WASMTIME_DWARF
