TryFrom(String, &'static str)

It’s is not possible to convert between the two types

TimestampOverflow(String)

Represents a failure in timestamp arithmetic related to database internals

Serialization(String)

The supplied type could not be serialized into expr::Value

Represents an arithmetic result that does not fit the value’s type

ArithmeticNegativeOverflow(String)

Represents a negative value for a type that must be zero or positive

InvalidBytesize

Implementations

impl Error

pub fn is_ignorable(&self) -> bool

Returns true if this error represents a data-shape problem (type mismatch, coercion failure, bad operand pair) that expression evaluation may resolve to NONE instead of propagating.

Returns false for everything else, including the arithmetic failures that are not listed. Membership is decided per variant and is not a family rule: TryDiv and TryPow are ignorable, TryRem and TryFrom are not. Do not widen the list to make it look tidy.

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.

impl From<CastError> for Error

fn from(source: CastError) -> Self

Converts to this type from the input type.

impl From<CoerceError> for Error

fn from(source: CoerceError) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<Error> for ControlFlow

fn from(error: Error) -> Self

Boxes the value-algebra failure directly, so it stays the concrete type in the anyhow slot and ControlFlow::is_ignorable keeps matching it.

impl LeafError for Error

fn map_kind(self, message: String) -> TypesError

Classify this error: kind, details and code.

fn to_types_error(self) -> Error

Produce the public error.
