Expand description

Result of background compilation.

Fields§

§function_id: u16

Function index that was compiled.

§compiled_tier: Tier

Tier that was compiled to.

§native_code: Option<*const u8>

Native code pointer if JIT compilation succeeded.

§error: Option<String>

Error message if compilation failed (function stays at current tier).

§osr_entry: Option<OsrEntryPoint>

If this is an OSR compilation, the entry point metadata.

§deopt_points: Vec<DeoptInfo>

Deopt info for all guard points in the compiled code. Each entry describes how to reconstruct interpreter state when a speculative guard fails inside the JIT-compiled code.

§loop_header_ip: Option<usize>

Bytecode IP of the loop header for OSR results. Used for blacklisting failed loops so compilation is not re-attempted.

§shape_guards: Vec<ShapeId>

Shape IDs guarded by this compilation. Used by DeoptTracker to invalidate the function when a guarded shape transitions.
