A trait bound of the supported error type of Exn.

Provided Methods

fn raise(self) -> Exn<Self>

where Self: Sized,

Raise this error as a new exception.

fn and_raise<T: Error + Send + Sync + 'static>(self, context: T) -> Exn<T>

where Self: Sized,

Raise this error as a child of a new exception with the given context error.

This is a shorthand for self.raise().raise(context) — it wraps self in an Exn and immediately nests it under a new Exn<T> headed by context.

// Instead of:
io_err.raise().raise(message("could not read file"))

// Write:
io_err.and_raise(message("could not read file"))

fn raise_erased(self) -> Exn

where Self: Sized,

Raise this error as a new exception, with type erasure.

fn raise_all<T, I>(self, sources: I) -> Exn<Self>

where Self: Sized, T: Error + Send + Sync + 'static, I: IntoIterator, I::Item: Into<Exn<T>>,

Raise this error as a new exception, with sources as causes.
