Enum StorageError 

pub enum StorageError {
    NotFound(String),
    PermissionDenied(String),
    Io(Error),
    InvalidKey(String),
    Backend(String),
    Timeout(String),
    Other(Error),
}

Errors that can occur during storage operations

Variants

NotFound(String)

Object not found in storage

PermissionDenied(String)

Permission denied for the requested operation

Io(Error)

I/O error occurred

InvalidKey(String)

Invalid key format (empty, contains invalid characters, etc.)

Backend(String)

Storage backend not available or misconfigured

Timeout(String)

Operation timed out

Other(Error)

Transparent error delegation for wrapped error types

This variant allows wrapping other error types (like anyhow::Error) while forwarding their Display and source implementations transparently. Useful for catch-all error handling and opaque error types.

Implementations

impl StorageError

pub fn not_found<S: Into<String>>(key: S) -> Self

Create a NotFound error with the given key

pub fn permission_denied<S: Into<String>>(msg: S) -> Self

Create a PermissionDenied error with context

pub fn invalid_key<S: Into<String>>(msg: S) -> Self

Create an InvalidKey error with context

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

Create a Backend error with context

pub fn timeout<S: Into<String>>(msg: S) -> Self

Create a Timeout error with context

pub fn other<E: Into<Error>>(error: E) -> Self

Create a generic error from any error type that can convert to anyhow::Error

pub fn is_not_found(&self) -> bool

Check if this is a NotFound error

pub fn is_permission_denied(&self) -> bool

Check if this is a PermissionDenied error

pub fn is_invalid_key(&self) -> bool

Check if this is an InvalidKey error

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<Error> for StorageError

fn from(source: Error) -> Self

Converts to this type from the input type.
