pub const structure: Struct = .{};

const module = @This();
pub const @"meta(zigar)" = struct {
    pub fn isFieldTypedArray(comptime T: type, comptime name: std.meta.FieldEnum(T)) bool {
        return T == Struct and name == .field;
    }
};

import { structure } from './meta-type-typed-array-example-2.zig';

console.log(structure.field);
