Struct SessionError 

pub struct SessionError { /* private fields */ }

Session-related errors

Design principles:

1. Small size: Uses boxed errors to keep struct size minimal (~24 bytes)
2. Full context: Preserves error chain
3. Clone support: Can be cloned for logging/propagation

Implementations

pub fn message(&self) -> &str

pub fn session_not_found(session_id: i64) -> Self

pub fn session_expired() -> Self

pub fn max_connections_exceeded() -> Self

pub fn query_not_found(query_id: u32) -> Self

pub fn kill_session_failed(message: impl Into<String>) -> Self

Trait Implementations

impl Clone for SessionError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SessionError

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

Formats the value using the given formatter.

impl Display for SessionError

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

Formats the value using the given formatter.

impl Error for SessionError

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<SessionError> for DBError

fn from(e: SessionError) -> Self

Converts to this type from the input type.

impl ToPublicError for SessionError

fn to_public_error(&self) -> PublicError

Convert to external error

fn to_error_code(&self) -> ErrorCode

Get external error codes

fn to_public_message(&self) -> String

Get external error messages (filter sensitive information)
