Enum DiskCacheError 

#[non_exhaustive]
pub enum DiskCacheError {
    CacheDirUnknown,
    Io(Error),
}

Errors from disk-backed pipeline cache construction / use.

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.

CacheDirUnknown

Neither $XDG_CACHE_HOME nor $HOME is set.

Io(Error)

std::io failure (mkdir, read, write).

Trait Implementations

impl Debug for DiskCacheError

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for DiskCacheError

fn from(source: Error) -> Self

Converts to this type from the input type.
