StructDecl

Trailing:

0. captures_len: u32 // if has_captures_len
1. fields_len: u32, // if has_fields_len
2. decls_len: u32, // if has_decls_len
3. capture: Capture // for every captures_len
4. capture_name: NullTerminatedString // for every captures_len
5. backing_int_body_len: u32, // if has_backing_int
6. backing_int_ref: Ref, // if has_backing_int and backing_int_body_len is 0
7. backing_int_body_inst: Inst, // if has_backing_int and backing_int_body_len is > 0
8. decl: Index, // for every decls_len; points to a declaration instruction
9. flags: u32 // for every 8 fields
   • sets of 4 bits: 0b000X: whether corresponding field has an align expression 0b00X0: whether corresponding field has a default expression 0b0X00: whether corresponding field is comptime 0bX000: whether corresponding field has a type expression
10. fields: { // for every fields_len field_name: u32, field_type: Ref, // if corresponding bit is not set. none means anytype. field_type_body_len: u32, // if corresponding bit is set align_body_len: u32, // if corresponding bit is set init_body_len: u32, // if corresponding bit is set }
11. bodies: { // for every fields_len field_type_body_inst: Inst, // for each field_type_body_len align_body_inst: Inst, // for each align_body_len init_body_inst: Inst, // for each init_body_len }
