Struct tsukuyomi::error::Error

pub struct Error(_);

A type which holds all kinds of errors occurring in handlers.

Implementations

impl Error

pub fn new(err: impl Into<Box<dyn HttpError>>) -> Self

Creates an Error from the specified value implementing HttpError.

pub fn critical(err: Critical) -> Self

Creates a critical error from an error value.

The word “critical” means that the error will not be converted into an HTTP response. If the framework receives this kind of error, it wlll abort the current connection abruptly without sending an HTTP response.

See the documentation at hyper for details.

pub fn is_critical(&self) -> bool

Returns true if this error is a critical error.

pub fn as_http_error(&self) -> Option<&dyn HttpError>

Returns the representation as HttpError of this error value by reference.

If the value is a criticial error, it will return a None.

pub fn into_http_error(self) -> Result<Box<dyn HttpError>, Critical>

Deconstructs self into inner error representation.

pub fn downcast<T: HttpError>(self) -> Result<T, Self>

Attempts to downcast this error value into the specified concrete type.

pub fn downcast_ref<T: HttpError>(&self) -> Option<&T>

Attempts to downcast this error value to the specified concrete type by reference.

pub fn downcast_mut<T: HttpError>(&mut self) -> Option<&mut T>

Attempts to downcast this error value to the specified concrete type by reference.

pub fn is<T: HttpError>(&self) -> bool

Returns true if the type of inner error value is equal to T.

Trait Implementations
