Struct HandlerError

pub struct HandlerError { /* private fields */ }

The HandlerError struct can be use to abstract any Err of the handler method Result. The HandlerError object can be generated From any object that supports Display, Send, Sync, and Debug. This allows handler functions to return any error using the ?syntax. For examplelet _age_num: u8 = e.age.parse()?;will return the::Err` from the handler function.

Implementations

impl HandlerError

pub fn new<T: Fail + LambdaErrorExt + Send + Sync>(e: T) -> Self

Trait Implementations

impl Debug for HandlerError

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

Formats the value using the given formatter.

impl Display for HandlerError

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

Formats the value using the given formatter.

impl Error for HandlerError

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)
