Struct tide::Error

pub struct Error { /* fields omitted */ }

The error type for HTTP operations.

Implementations

impl Error

pub fn new<S, E>(status: S, error: E) -> Error where
    S: TryInto<StatusCode>,
    E: Into<Error>,
    <S as TryInto<StatusCode>>::Error: Debug, 

Create a new error object from any error type.

The error type must be threadsafe and 'static, so that the Error will be as well. If the error type does not provide a backtrace, a backtrace will be created here to ensure that a backtrace exists.

pub fn from_str<S, M>(status: S, msg: M) -> Error where
    S: TryInto<StatusCode>,
    M: Display + Debug + Send + Sync + 'static,
    <S as TryInto<StatusCode>>::Error: Debug, 

Create a new error object from static string.

pub fn status(&self) -> StatusCode

Get the status code associated with this error.

pub fn set_status<S>(&mut self, status: S) where
    S: TryInto<StatusCode>,
    <S as TryInto<StatusCode>>::Error: Debug, 

Set the status code associated with this error.

pub fn backtrace(&self) -> Option<&Backtrace>

Get the backtrace for this Error.

Backtraces are only available on the nightly channel. Tracking issue: rust-lang/rust#53487.

In order for the backtrace to be meaningful, the environment variable RUST_LIB_BACKTRACE=1 must be defined. Backtraces are somewhat expensive to capture in Rust, so we don't necessarily want to be capturing them all over the place all the time.

Note: This function can be called whether or not backtraces are enabled and available. It will return a None variant if compiled on a toolchain that does not support backtraces, or if executed without backtraces enabled with RUST_LIB_BACKTRACE=1.

pub fn into_inner(self) -> Error

Returns the inner [anyhow::Error] Note: This will lose status code information

pub fn downcast<E>(self) -> Result<E, Error> where
    E: Display + Debug + Send + Sync + 'static, 

Attempt to downcast the error object to a concrete type.

pub fn downcast_ref<E>(&self) -> Option<&E> where
    E: Display + Debug + Send + Sync + 'static, 

Downcast this error object by reference.

pub fn downcast_mut<E>(&mut self) -> Option<&mut E> where
    E: Display + Debug + Send + Sync + 'static, 

Downcast this error object by mutable reference.

pub fn type_name(&self) -> Option<&str>

Retrieves a reference to the type name of the error, if available.
