Enum LandCacheError 

pub enum LandCacheError {
    Store(StoreError),
    Database(Error),
    Io(Error),
    NoCoverage,
}

Everything that can go wrong baking a chart’s land cache.

Variants

Store(StoreError)

Reading the source chart failed.

Database(Error)

Writing or reading the cache file itself failed.

Io(Error)

The source chart’s own file metadata could not be read.

NoCoverage

The chart carries no COVERAGE_CLASS features at all, so detect_coverage_area has nothing to detect a region from.

Trait Implementations
