A tuple struct or tuple variant was used in a pattern as if it were a struct or
struct variant.
Erroneous code example:
#![allow(unused)]
fn main() {
enum E {
A(i32),
}
let e = E::A(42);
match e {
E::A { number } => {
println!("{}", number);
}
}
}
ⓘ
To fix this error, you can use the tuple pattern:
#![allow(unused)]
fn main() {
enum E {
A(i32),
}
let e = E::A(42);
match e {
E::A(number) => {
println!("{}", number);
}
}
}
Alternatively, you can also use the struct pattern by using the correct field
names and binding them to new identifiers:
#![allow(unused)]
fn main() {
enum E {
A(i32),
}
let e = E::A(42);
match e {
E::A { 0: number } => {
println!("{}", number);
}
}
}
