Errors that can happen when interacting with an Environment.

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.

EnvVarExceedsLimits

A variable exceeds the limits of its type.

Fields

name: ConstString

Name of the variable

EnvVarNotDefined

A variable has not been defined/created in the Environment.

Fields

name: ConstString

Name of the variable

EnvVarUnknownType

A variable has an unkown type.

Fields

name: ConstString

Name of the variable

EnvVarWrongType

A variable has a different type than in the Environment.

Fields

name: ConstString

Name of the variable

EnvVarSet

An external error when setting the variable.

Fields

name: ConstString

Name of the variable

cause: ConstString

Cause of error

EnvVarTypeCast

An error when casting the type of the variable.

Fields

name: ConstString

Name of the variable

var_type: ConstString

Expected type ofthe variable

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

Currently the default implementation is sufficient.

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 ExecutionError

fn from(error: Error) -> Self

Converts to this type from the input type.
