Struct pavex::Error

pub struct Error { /* private fields */ }

Pavex’s error type: an opaque wrapper around the concrete error type return by your components (e.g. request handlers, constructors, etc.). It is used as an input parameter by error observers and universal error handlers.

Implementation details

It’s a thin shim over Box<dyn std::error::Error + Send + Sync>.

Implementations

impl Error

pub fn new<E>(error: E) -> Self

where E: Into<Box<dyn Error + Send + Sync>>,

Create a new Error from a boxable error.

pub fn into_inner(self) -> Box<dyn Error + Send + Sync>

Convert Error back into the underlying boxed error.

pub fn inner_ref(&self) -> &(dyn Error + Send + Sync)

Return a reference to the underlying boxed error.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
