Implementations

impl Error

pub fn timeout(duration_ms: u64) -> Self

Create a timeout error with the specified duration in milliseconds

pub fn concurrent_modification<S: Into<String>>(context: S) -> Self

Create a concurrent modification error with context

pub fn pool_exhausted() -> Self

Create a pool exhausted error

pub fn is_timeout(&self) -> bool

Check if this error is a timeout

pub fn is_concurrent_modification(&self) -> bool

Check if this error is a concurrent modification

pub fn is_pool_exhausted(&self) -> bool

Check if this error is pool exhausted

pub fn is_retryable(&self) -> bool

Check if this error is retryable

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
