|
|||
|
|
<p>Implementors of this trait are called 'failures'.</p>
|
|||
|
|
<p>All error types should implement <code>Fail</code>, which provides a baseline of
|
|||
|
|
functionality that they all share.</p>
|
|||
|
|
<p><code>Fail</code> has no required methods, but it does require that your type
|
|||
|
|
implement several other traits:</p>
|
|||
|
|
<ul>
|
|||
|
|
<li><code>Display</code>: to print a user-friendly representation of the error.</li>
|
|||
|
|
<li><code>Debug</code>: to print a verbose, developer-focused representation of the
|
|||
|
|
error.</li>
|
|||
|
|
<li><code>Send + Sync</code>: Your error type is required to be safe to transfer to and
|
|||
|
|
reference from another thread</li>
|
|||
|
|
</ul>
|
|||
|
|
<p>Additionally, all failures must be <code>'static</code>. This enables downcasting.</p>
|
|||
|
|
<p><code>Fail</code> provides several methods with default implementations. Two of these
|
|||
|
|
may be appropriate to override depending on the definition of your
|
|||
|
|
particular failure: the <code>cause</code> and <code>backtrace</code> methods.</p>
|
|||
|
|
<p>The <code>failure_derive</code> crate provides a way to derive the <code>Fail</code> trait for
|
|||
|
|
your type. Additionally, all types that already implement
|
|||
|
|
<code>std::error::Error</code>, and are also <code>Send</code>, <code>Sync</code>, and <code>'static</code>, implement
|
|||
|
|
<code>Fail</code> by a blanket impl.</p>
