Enum TaskStorageError 

pub enum TaskStorageError {
    TaskNotFound(String),
    InvalidTransition {
        current: TaskStatus,
        requested: TaskStatus,
    },
    TerminalState(TaskStatus),
    TaskExpired(String),
    MaxTasksReached(usize),
    ConcurrentModification(String),
    DatabaseError(String),
    SerializationError(String),
    Generic(String),
}

Unified error type for task storage operations.

Mirrors the pattern used in turul-mcp-session-storage for consistency.

Trait Implementations

impl Debug for TaskStorageError

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

Formats the value using the given formatter.

impl Display for TaskStorageError

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

Formats the value using the given formatter.

impl Error for TaskStorageError

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 TaskStorageError

fn from(err: Error) -> Self

Converts to this type from the input type.
