Overview

One entry in a function’s catch table. Positions are references to IR::Instruction objects by identity, so mutations to the instruction list don’t invalidate them.

type         — one of :rescue, :ensure, :retry, :break, :redo, :next
iseq_index   — index into the iseq-list for the handler iseq
               (nil for entries without a handler iseq, such as :retry)
start_inst   — IR::Instruction marking the start of the covered range
end_inst     — IR::Instruction marking the end (exclusive)
cont_inst    — IR::Instruction where control resumes after handling
               (always present; for :retry entries this points to slot 0)
stack_depth  — operand-stack depth at which the handler runs
