Enum StoreError 

#[non_exhaustive]
pub enum StoreError {
    PathNotFound(String),
    Database(String),
    Http(String),
    NarInfo(String),
    Io(Error),
    NotSupported(String),
    Internal(String),
}

Store operation errors.

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.

PathNotFound(String)

The requested store path does not exist.

Database(String)

A database or backend operation failed.

Http(String)

An HTTP request to a binary cache failed.

NarInfo(String)

A NarInfo response could not be parsed.

Io(Error)

An I/O operation failed.

NotSupported(String)

The operation is not supported by this store backend.

Internal(String)

An internal invariant was violated.

Implementations

impl StoreError

pub fn is_path_not_found(&self) -> bool

Returns true if this is a PathNotFound error.

pub fn is_not_supported(&self) -> bool

Returns true if this is a NotSupported error.

Trait Implementations

impl Debug for StoreError

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

Formats the value using the given formatter.

impl Display for StoreError

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

Formats the value using the given formatter.

impl Error for StoreError

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 StoreError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<HttpError> for StoreError

fn from(e: HttpError) -> Self
