The changes were mostly automatically applied using the following
Python script:

```python
import os, re

for root, _, files in os.walk("."):
    for f in files:
        if not f.endswith(".rs"):
            continue
        p = os.path.join(root, f)
        with open(p, "r", encoding="utf-8") as file:
            lines = file.readlines()
        changed = False
        for i in range(len(lines) - 1):
            if re.search(r'#\[error\(".*: \{0[^}]*\}"\)\]', lines[i]) and "#[source]" in lines[i + 1].strip():
                lines[i] = re.sub(r': \{0[^}]*\}"\)\]', '")]', lines[i])
                changed = True
        if changed:
            with open(p, "w", encoding="utf-8") as file:
                file.writelines(lines)
            print("Fixed:", p)
