Error code E0124

A struct was declared with two fields having the same name.

Erroneous code example:

#![allow(unused)]
fn main() {
struct Foo {
    field1: i32,
    field1: i32, // error: field is already declared
}
}
ⓘ

Please verify that the field names have been correctly spelled. Example:

#![allow(unused)]
fn main() {
struct Foo {
    field1: i32,
    field2: i32, // ok!
}
}
