Error Code 014

Overview

This error occurs when the compiler encounters multiple function overloads that match a given call, and it cannot determine which one to use. This is often caused by overlapping or ambiguous parameter types in the overloads.

Details

  • Common Causes:

    • Overloading functions with parameters that can implicitly convert to other types.
    • Ambiguous calls where the compiler cannot decide which function to use.

  • Example:

void foo(int x) {
    writeln("Called foo(int)");
}

void foo(float x) {
    writeln("Called foo(float)");
}

void main() {
    foo(42); // Error: ambiguous call
}
  • Solution:
    • Use explicit casting to resolve ambiguity: 
      void main() {
    foo(cast(int) 42); // Explicitly call foo(int)
}
    • Avoid ambiguous overloads by designing the function signatures to be more distinct: 
      void foo(int x) {
    writeln("Called foo(int)");
}

void foo(string x) {
    writeln("Called foo(string)");
}

void main() {
    foo(42); // Calls foo(int)
}
