E0025: Pattern Enum Mismatch

The enum in your pattern doesn't match the type of the value being matched.

Example

enum Color {
    Red,
    Green,
}

enum Status {
    Active,
    Inactive,
}

fn check(c: Color) -> i64 {
    match c {
        Status::Active => { 1 },  // Error: pattern references enum `Status` but scrutinee has type `Color`
        Status::Inactive => { 0 },
    }
}

How to fix

Use patterns from the correct enum:

enum Color {
    Red,
    Green,
}

fn check(c: Color) -> i64 {
    match c {
        Color::Red => { 1 },
        Color::Green => { 0 },
    }
}
