Implementations

impl ExprError

pub fn function<'a>( fn_name: &str, args: impl IntoIterator<Item = DatumRef<'a>>, source: impl Into<Box<dyn Error + Send + Sync>>, ) -> Self

Constructs a ExprError::Function error with the given information for display.

Trait Implementations

impl Debug for ExprError

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

Formats the value using the given formatter.

impl Display for ExprError

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

Formats the value using the given formatter.

impl Error for ExprError

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

Returns the lower-level source of this error, if any.

fn provide<'_request>(&'_request self, request: &mut Request<'_request>)

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

Provides type-based access to context intended for error reports.

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
