Struct DMSCLockError 

pub struct DMSCLockError { /* private fields */ }

Specialized error type for lock-related failures.

This error type provides detailed information about lock acquisition failures, including whether the lock was poisoned or simply contested. The error includes context about the lock’s purpose for better debugging.

Implementations

impl DMSCLockError

pub fn new(context: &str) -> Self

Creates a new lock error with the given context.

Arguments

context: Human-readable description of what was being locked

Returns

A new `DMSCLockError` instance

pub fn poisoned(context: &str) -> Self

Creates a poisoned lock error.

Arguments

context: Human-readable description of what was being locked

Returns

A new `DMSCLockError` instance marked as poisoned

pub fn get_context(&self) -> &str

Gets the context message for this lock error.

Trait Implementations

impl Clone for DMSCLockError

fn clone(&self) -> DMSCLockError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DMSCLockError

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

Formats the value using the given formatter.

impl Display for DMSCLockError

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

Formats the value using the given formatter.

impl Error for DMSCLockError

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<DMSCLockError> for DMSCError

fn from(error: DMSCLockError) -> Self

Converts to this type from the input type.

impl Hash for DMSCLockError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'py> IntoPyObject<'py> for DMSCLockError

type Target = DMSCLockError

The Python output type

type Output = Bound<'py, <DMSCLockError as IntoPyObject<'py>>::Target>

The smart pointer type to use.

type Error = PyErr

The type returned in the event of a conversion error.

fn into_pyobject( self, py: Python<'py>, ) -> Result<<Self as IntoPyObject<'_>>::Output, <Self as IntoPyObject<'_>>::Error>

Performs the conversion.

impl PartialEq for DMSCLockError

fn eq(&self, other: &DMSCLockError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PyClass for DMSCLockError

type Frozen = False

Whether the pyclass is frozen.

impl PyClassImpl for DMSCLockError

const IS_BASETYPE: bool = false

#[pyclass(subclass)]

const IS_SUBCLASS: bool = false

#[pyclass(extends=…)]

const IS_MAPPING: bool = false

#[pyclass(mapping)]

const IS_SEQUENCE: bool = false

#[pyclass(sequence)]

const IS_IMMUTABLE_TYPE: bool = false

#[pyclass(immutable_type)]

const RAW_DOC: &'static CStr = /// context about the lock's purpose for better debugging.

Docstring for the class provided on the struct or enum.

const DOC: &'static CStr

Fully rendered class doc, including the text_signature if a constructor is defined.

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<DMSCLockError>

This handles following two situations:

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild

Immutable or mutable

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.
