|
||
<p>Depending on a compilation flag, the content of the <code>Context</code> enum
|
||
can change. In the default case, it will only have one variant:
|
||
<code>Context::Code(I, ErrorKind<E=u32>)</code> (with <code>I</code> and <code>E</code> configurable).
|
||
It contains an error code and the input position that triggered it.</p>
|
||
<p>If you activate the <code>verbose-errors</code> compilation flags, it will add another
|
||
variant to the enum: <code>Context::List(Vec<(I, ErrorKind<E>)>)</code>.
|
||
This variant aggregates positions and error codes as the code backtracks
|
||
through the nested parsers.
|
||
The verbose errors feature allows for very flexible error management:
|
||
you can know precisely which parser got to which part of the input.
|
||
The main drawback is that it is a lot slower than default error
|
||
management.</p>
