Implementations

impl CalError

pub fn try_downcast<E>(self) -> Result<E, Self> where
    E: Display + Debug + Send + Sync + 'static, 

Try to downcast the error into a concrete type, if the error is a CalError::Other.

Errors

self is returned if the error could not be downcast.

#[must_use]

pub fn try_downcast_ref<E>(&self) -> Option<&E> where
    E: Display + Debug + Send + Sync + 'static, 

Try to downcast a reference to the error into a reference to a concrete type, if the error is a CalError::Other.

pub fn try_downcast_mut<E>(&mut self) -> Option<&mut E> where
    E: Display + Debug + Send + Sync + 'static, 

Try to downcast a mutable reference to the error into a mutable reference to a concrete type, if the error is a CalError::Other.

Trait Implementations

impl Debug for CalError

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

Formats the value using the given formatter.

impl Display for CalError

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

Formats the value using the given formatter.

impl Error for CalError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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
