Enum PackageCacheError

#[non_exhaustive]
pub enum PackageCacheError {
    Cancelled,
    LayerError(Box<dyn Error + Send + Sync>),
    NoWritableLayers,
}

Errors specific to the PackageCache interface

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.

Cancelled

The operation was cancelled

LayerError(Box<dyn Error + Send + Sync>)

An error occurred in a cache layer

NoWritableLayers

There are no writable layers to cache package to

Trait Implementations

impl Debug for PackageCacheError
