The compiler team's explanation
An unknown field was specified into an enum's structure variant.
Erroneous code example:
enum Field {
Fool { x: u32 },
}
let s = Field::Fool { joke: 0 };
// error: struct variant `Field::Fool` has no field named `joke`Verify you didn't misspell the field's name or that the field exists. Example:
enum Field {
Fool { joke: u32 },
}
let s = Field::Fool { joke: 0 }; // ok!From rustc --explain E0559 (1.99.0), part of the Rust project, MIT or Apache-2.0. Official page.
