E0014: Duplicate Struct Field

A struct definition contains the same field name more than once.

Example​

struct Point {
    x: i64,
    y: i64,
    x: i64,  // Error: field `x` appears multiple times in struct `Point`
}

How to fix​

Remove the duplicate field or give it a unique name:

struct Point {
    x: i64,
    y: i64,
    z: i64,  // OK
}
