ChainError

Enum ChainError 

Source
pub enum ChainError<A, B> {
    Both(A, B),
}
Expand description

Combined error from two chained loaders.

The second loader is only consulted after the first has failed, so a chain failure always carries both errors.

Variants§

§

Both(A, B)

Both loaders failed.
