Module opcode_tracer 

Structs

LevmOpcodeTracer

Per-opcode (EIP-3155) tracer, emitted under the de-facto cross-client structLogger wrapper shape.

OpcodeTracerConfig

Configuration for the per-opcode (EIP-3155) tracer.

Functions

build_step

Constructs an OpcodeStep from raw VM state. Shared between the dispatch-loop hook (pre_step_capture) and synthetic-step builders (e.g. fused JUMPDEST under JUMP/JUMPI). Callers pass gas_cost = 0 when they intend to patch it later in finalize_step; synthetic steps pass the known cost directly.
