Enum CoverageError 

#[non_exhaustive]
pub enum CoverageError {
    Backend(String),
}

Errors a coverage backend can return.

Variants (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.

Backend(String)

The durable backing could not be reached or written.
