Enum StorageError 

pub enum StorageError {
    NotFound(String),
    InvalidKey(String),
    Unsupported(String),
    Io(Error),
    Backend(String),
}

Errors that can occur while interacting with a crate::Storage backend.

Variants

NotFound(String)

The requested key does not exist.

InvalidKey(String)

The key was rejected (e.g. a path-traversal attempt).

Unsupported(String)

The backend does not support this operation yet.

Io(Error)

An underlying I/O error.

Backend(String)

A backend-specific error.

Implementations

impl StorageError

pub fn unsupported(msg: impl Into<String>) -> Self

Convenience constructor for StorageError::Unsupported.

pub fn backend(msg: impl Into<String>) -> Self

Convenience constructor for StorageError::Backend.

Trait Implementations

impl Debug for StorageError

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

Formats the value using the given formatter.

impl Display for StorageError

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

Formats the value using the given formatter.

impl Error for StorageError

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 StorageError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<StorageError> for DeployError

fn from(source: StorageError) -> Self

Converts to this type from the input type.
