next
Function parameters
Parameters
- it:*DeclIterator
The data stored at byte offset 0 when ZIR is stored in a file.
Types
- Header
- The data stored at byte offset 0 when ZIR is stored in a file.
- Inst
- These are untyped instructions generated from an Abstract Syntax Tree.
- DeclContents
- `DeclContents` contains all "interesting" instructions found within a declaration by `findTrackable`.
Returns the requested data, as well as the new index which is at the start of the
Functions
- extraData
- Returns the requested data, as well as the new index which is at the start of the
- nullTerminatedString
- Given an index into `string_bytes` returns the null-terminated string found there.
- findTrackable
- Find all tracked ZIR instructions, recursively, within a `declaration` instruction.
- findTrackableRoot
- Like `findTrackable`, but only considers the `main_struct_inst` instruction.
- assertTrackable
- Asserts that a ZIR instruction is tracked across incremental updates, and
When the ZIR update tracking logic must be modified to consider new instructions,
Values
- inst_tracking_version
- When the ZIR update tracking logic must be modified to consider new instructions,
