Enum cached_path::Error

pub enum Error {
    ResourceNotFound(String),
    InvalidUrl(String),
    NoCachedVersions(String),
    CacheCorrupted(String),
    ExtractionError(String),
    IoError(Error),
    HttpStatusError(u16),
    HttpTimeoutError,
    HttpBuilderError,
    HttpError,
}

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.

HttpStatusError(u16)

Arises when a bad HTTP status code is received while attempting to fetch a remote resource.

HttpTimeoutError

Arises when an HTTP timeout error occurs while attempting to fetch a remote resource.

HttpBuilderError

Arises when the HTTP client fails to build.

HttpError

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

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)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Error> for Error

fn from(source: Error) -> Self

Performs the conversion.

impl From<Error> for Error

fn from(err: Error) -> Error
