Struct TimerError 

pub struct TimerError { /* private fields */ }

Represents timer-related failures.

Implementations

impl TimerError

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

Creates an invalid parameter error.

pub fn not_running() -> Self

Creates an error for operations that require a running timer.

pub fn not_paused() -> Self

Creates an error for operations that require a paused timer.

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

Creates an error for operations that cannot safely run from the active callback.

pub fn callback_timed_out(timeout: Duration) -> Self

Creates an error for callback timeout expiration.

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

Creates an error for callback execution failures.

pub fn is_invalid_parameter(&self) -> bool

Returns true when the error is an invalid parameter error.

pub fn invalid_parameter_message(&self) -> Option<&str>

Returns the invalid parameter message when available.

pub fn is_not_running(&self) -> bool

Returns true when the error indicates the timer was not running.

pub fn is_not_paused(&self) -> bool

Returns true when the error indicates the timer was not paused.

pub fn is_reentrant_operation(&self) -> bool

Returns true when the error indicates a reentrant callback operation.

pub fn reentrant_operation_message(&self) -> Option<&str>

Returns the reentrant-operation message when available.

pub fn is_callback_failed(&self) -> bool

Returns true when the error indicates callback execution failed.

pub fn is_callback_timed_out(&self) -> bool

Returns true when the error indicates callback execution timed out.

pub fn callback_timeout(&self) -> Option<Duration>

Returns the callback timeout when available.

pub fn callback_failure_message(&self) -> Option<&str>

Returns the callback failure message when available.

pub fn backtrace(&self) -> &Backtrace

Returns the captured backtrace.

Trait Implementations

impl Clone for TimerError

fn clone(&self) -> TimerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TimerError

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

Formats the value using the given formatter.

impl Display for TimerError

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

Formats the value using the given formatter.

impl Error for TimerError

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 PartialEq for TimerError

fn eq(&self, other: &Self) -> 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.
