This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig standard library. Private Type Function

Private Type Function

std.zon.parse.Parser.failComptimeField

fn failComptimeField(
        self: @This(),
        node: Zoir.Node.Index,
        field: usize,
    ) error

Technically we could do this if we were willing to do a deep equal to verify the value matched, but doing so doesn't seem to support any real use cases so isn't worth the complexity at the moment.
