E118: Params No Inline

This error is emitted when the inline modifier is used on parameters of a non-inline method.

The inline modifier on parameters is only allowed for parameters of inline methods, where it enables the parameter to be inlined at the call site.

Example

scala

def example(inline x: Int): Int = x + 1

Error

scala

-- [E118] Syntax Error: example.scala:1:19 -------------------------------------
1 |def example(inline x: Int): Int = x + 1
  |                   ^
  |         inline modifier can only be used for parameters of inline methods

Solution

scala

// Make the method inline as well
inline def example(inline x: Int): Int = x + 1

scala

// Or remove inline from the parameter
def example(x: Int): Int = x + 1
