Each row contains unwinding rules for a set of registers.

Fields

offset: u64 = 0,

Offset from FrameDescriptionEntry.pc_begin

cfa: Column = .{ },

Special-case column that defines the CFA (Canonical Frame Address) rule. The register field of this column defines the register that CFA is derived from.

columns: ColumnRange = .{ },

The register fields in these columns define the register the rule applies to.

copy_on_write: bool = false,

Indicates that the next write to any column in this row needs to copy the backing column storage first, as it may be referenced by previous rows.
