Enum Error 

pub enum Error {
    ResourceNotFound(String),
    InvalidUrl(String),
    NoCachedVersions(String),
    CacheCorrupted(String),
    ExtractionError(String),
    IoError(Error),
    HttpError(Error),
    ConfigurationError(String),
}

Errors that can occur during caching.

Variants

ResourceNotFound(String)

Arises when the resource looks like a local file but it doesn’t exist.

InvalidUrl(String)

Arises when the resource looks like a URL, but is invalid.

NoCachedVersions(String)

Arises when the cache is being used in offline mode, but it couldn’t locate any cached versions of a remote resource.

CacheCorrupted(String)

Arises when the cache is corrupted for some reason.

If this error occurs, it is almost certainly the result of an external process “messing” with the cache directory, since cached-path takes great care to avoid accidental corruption on its own.

ExtractionError(String)

Arises when a resource is treated as archive, but the extraction process fails.

IoError(Error)

Any IO error that could arise while attempting to cache a remote resource.

HttpError(Error)

An HTTP error that could occur while attempting to fetch a remote resource.

ConfigurationError(String)

Raise when configuration options are invalid.

Implementations

impl Error

pub fn status_code(&self) -> Option<u16>

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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 Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self
