Variants (Non-exhaustive)

[+] This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl Error[−]

[+] Expand attributes

#[must_use]pub fn positions(&self) -> ErrorPositions[−]
