<p>This simplifies creation of an anyhow::Result in places where type inference
|
|
|
|
|
cannot deduce the <code>E</code> type of the result — without needing to write
|
|
|
|
|
<code>Ok::<_, anyhow::Error>(value)</code>.</p>
|
|
|
|
|
<p>One might think that <code>anyhow::Result::Ok(value)</code> would work in such cases
|
|
|
|
|
but it does not.</p>
