Bracket that is never closed

Built from the repository at commit a8614dc.

Every (, [ and { needs its closing bracket before the end of the file. The error points at the innermost bracket that is still open.

Why

A missing closing bracket changes what every later line means, so the compiler stops at the end of the file and names the bracket that never closed.

Broken

fn main() {
    print(1)

What sisu says

error[E0003]: unclosed `{`
 --> E0003.sisu:1:11
  |
1 | fn main() {
  |           ^

sisu: 1 error
sisu: for more on a code, run `sisu explain <code>`: E0003

Fixed

fn main() {
    print(1)
}
