Expand description

Errors that qsu will return to application.

Variants§

§

App(AppErr)

Application-defined error.

Applications can use this variant to pass application-specific errors through the runtime back to itself.

§

ArgP(ArgsError)

§

BadFormat(String)

§

Internal(String)

§

IO(String)

§

LumberJack(String)

An error related to logging occurred.

This includes both initialization and actual logging.

On Windows errors such as failure to register an event source will be treated as this error variant as well.

§

Missing(String)

Missing expected data.

§

Rocket(String)

Available on crate feature rocket only.

Rocket-specific errors.

§

SubSystem(String)

§

SrvApp(AppErrors)

Available on crate feature rt only.

Returned by RunCtx::run() to indicate which server application callbacks that failed.

§

Unsupported

Implementations§

source§

impl Error

source

pub fn is_apperr(&self) -> bool

source

pub fn try_into_apperr<E>(self) -> Result<E, Error>
where E: Error + Blessed + 'static,

Attempt to convert Error into application-specific error.

If it’s not an Error::App() nor can be downcast to type E, the error will be returned back as an Err().

source

pub fn unwrap_apperr<E>(self) -> E
where E: Error + Blessed + 'static,

Unwrap application-specific error from an Error.

§Panic

Panics if Error variant is not Error::App().

§

fn quirk(&self, value: Quirk) -> Painted<&T>
