Enum calypso_diagnostic::prelude::CalError

#[non_exhaustive]
pub enum CalError {
    Io(Error),
    FromUtf8(FromUtf8Error),
    Fmt(Error),
    Other(Report),
}

The Calypso error type.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Io(Error)

IO errors

FromUtf8(FromUtf8Error)

UTF-8 decoding errors

Fmt(Error)

Formatting errors

Other(Report)

Any other error, using eyre

Implementations

impl CalError

pub fn try_downcast<E>(self) -> Result<E, CalError>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.

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<(), Error>

Formats the value using the given formatter.

impl Display for CalError

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

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 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, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.
