Overview

One entry in an iseq’s line-info table.

inst         — the IR::Instruction whose start slot is at or before this entry's
               YARV slot position. For most entries this is the instruction annotated
               by this line entry. For "adjust" entries (added by CRuby for continuation
               points after block calls), the slot may fall inside an instruction's
               operand range — in that case inst is the containing instruction and
               slot_offset records the delta from that instruction's start slot.
slot_offset  — delta from inst's YARV start slot to the actual insns_info slot
               position. 0 for the vast majority of entries; >0 only for adjust-
               style entries that point to a mid-instruction YARV slot.
line_no      — source line number (1-based), absolute (not delta-encoded)
node_id      — parser node id (opaque integer; preserved on round-trip)
events       — flags bitmap for tracepoint events (RUBY_EVENT_LINE, etc.)
