findTrackableRoot

Like findTrackable, but only considers the main_struct_inst instruction. This may return more than just that instruction because it will also traverse fields.

Function parameters

Parameters

#
contents:*DeclContents

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,

pub fn findTrackableRoot(zir: Zir, gpa: Allocator, contents: *DeclContents) !void {

    defer found_defers.deinit(gpa);

    try zir.findTrackableInner(gpa, contents, &found_defers, .main_struct_inst);
