Enum PathError 

pub enum PathError {
    FrameIsNotAMessage,
    IncorrectActionContext,
    FailedToCapture(String),
    DeserializationFailure(Error),
}

These errors can occur when trying to deserialize frame messages.

Variants

FrameIsNotAMessage

Sometimes the frame isn’t a message when we expect it to be.

IncorrectActionContext

Sometimes the path extraction is attempted with the wrong kind of system.

FailedToCapture(String)

Sometimes the path we’ve been given doesn’t have any captures. This is an error because we can’t proceed and attempt to deserialize if so.

DeserializationFailure(Error)

Sometimes the path extraction fails to capture the given types. This can happen for a number of reasons, the most likely being that the type we’ve been given isn’t a tuple and the consumer tried to extract a single type that wasn’t friendly with the fact that we need to deserialize lists.

Trait Implementations

impl Debug for PathError

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

Formats the value using the given formatter.

impl Display for PathError

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

Formats the value using the given formatter.

impl Error for PathError

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 PathError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<PathError> for ExtractorError

fn from(source: PathError) -> Self

Converts to this type from the input type.
