    StarlarkEvalError(String),
    StarlarkConversionError(String),
    DeserializationError(Error),
    ExpectedOneValueFoundMany,

}

Errors that can occur when compiling expressions.

Variants

JmespathError(JmespathError)

The JMESPath expression is invalid or failed to evaluate.

StarlarkParseError(String)

The Starlark expression failed to parse.

StarlarkEvalError(String)

The Starlark expression failed to evaluate.

StarlarkConversionError(String)

The Starlark result could not be converted to JSON.

DeserializationError(Error)

The expression result could not be deserialized to the expected type.

ExpectedOneValueFoundMany

Expected a single value but the expression returned multiple.

UnsupportedSpecial

A Special expression variant is not supported for this target type.

Trait Implementations

impl Debug for ExpressionError

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

Formats the value using the given formatter.

impl Display for ExpressionError

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

Formats the value using the given formatter.

impl Error for ExpressionError

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<Error> for ExpressionError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<JmespathError> for ExpressionError

fn from(source: JmespathError) -> Self

Converts to this type from the input type.
