# SIFR-RESULT-0001: Unused Result value.

> Unused Result value.

`SIFR-RESULT-0001` belongs to the **Result and typed errors** diagnostic family. It means: unused Result value.

## Why It Happens

A typed failure path is being ignored or described with an invalid error type. Handle the `Result`, propagate it, or use a valid error type.

<Info>
  Use `sifr --explain SIFR-RESULT-0001` locally to see the renderer's exact message template and any machine-applicable suggestions for the compiler version you are running.
</Info>

## Erroneous Code

```python theme={null}
read_text("notes.txt")
```

## How To Fix It

Handle typed failures explicitly. Use `try`/`except`, return the `Result`, or otherwise consume the value so failures cannot be ignored.

## Fixed Code

```python theme={null}
try:
    text = read_text("notes.txt")
except IOError as e:
    text = ""
```
