struct Context [src]

Expressions can be evaluated in different contexts, each requiring its own set of inputs. Callers should specify all the fields relevant to their context. If a field is required by the expression and it isn't in the context, error.IncompleteExpressionContext is returned.

Fields

format: std.dwarf.Format = .@"32"The dwarf format of the section this expression is in

memory_accessor: ?*std.debug.MemoryAccessor = nullIf specified, any addresses will pass through before being accessed

compile_unit: ?*const std.debug.Dwarf.CompileUnit = nullThe compilation unit this expression relates to, if any

object_address: ?*const anyopaque = nullWhen evaluating a user-presented expression, this is the address of the object being evaluated

debug_addr: ?[]const u8 = null.debug_addr section

thread_context: ?*std.debug.ThreadContext = nullThread context

reg_context: ?abi.RegisterContext = null

cfa: ?usize = nullCall frame address, if in a CFI context

entry_value_context: bool = falseThis expression is a sub-expression from an OP.entry_value instruction
