An array without a fixed length was pattern-matched.
Erroneous code example:
#![allow(unused)]
fn main() {
fn is_123<const N: usize>(x: [u32; N]) -> bool {
match x {
[1, 2, ..] => true,
_ => false
}
}
}

To fix this error, you have two solutions:
- Use an array with a fixed length.
- Use a slice.
Example with an array with a fixed length:
#![allow(unused)]
fn main() {
fn is_123(x: [u32; 3]) -> bool {
match x {
[1, 2, ..] => true,
_ => false
}
}
}
Example with a slice:
#![allow(unused)]
fn main() {
fn is_123(x: &[u32]) -> bool {
match x {
[1, 2, ..] => true,
_ => false
}
}
}
