Function fromZoirNode [src]

Like fromZoir, but the parse starts at node instead of root.

Prototype

 pub fn fromZoirNode( T: type, ast: Ast, zoir: Zoir, node: Zoir.Node.Index, diag: ?*Diagnostics, options: Options, ) error{ParseZon}!T

Parameters

T: typeast: Astzoir: Zoirnode: Zoir.Node.Indexdiag: ?*Diagnosticsoptions: Options

Possible Errors

  pub fn fromZoirNode(
    T: type,
    ast: Ast,
    zoir: Zoir,
    node: Zoir.Node.Index,
    diag: ?*Diagnostics,
    options: Options,
) error{ParseZon}!T {
    comptime assert(!requiresAllocator(T));
    var buf: [0]u8 = .{};
    var failing_allocator = std.heap.FixedBufferAllocator.init(&buf);
    return fromZoirNodeAlloc(
        T,
        failing_allocator.allocator(),
        ast,
        zoir,
        node,
        diag,
        options,
    ) catch |err| switch (err) {
        error.OutOfMemory => unreachable, // Checked by comptime assertion above
        else => |e| return e,
    };
}
