Struct Error

pub struct Error { /* private fields */ }

The type of error that can be returned in this crate.

Instead of implementing the Error trait provided by the standard library, it implemented the Fail trait provided by the failure crate. Doing so means that this type guaranteed to be both sendable and usable across threads, and that you’ll be able to use the downcasting feature of the failure::Error type.

Implementations

impl Error

pub fn kind(&self) -> &ErrorKind

Return the underlying ErrorKind

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Fail for Error

fn cause(&self) -> Option<&(dyn Fail + 'static)>

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

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

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn name(&self) -> Option<&str>

Returns the “name” of the error.

fn context<D>(self, context: D) -> Context<D>

where D: Display + Send + Sync + 'static, Self: Sized,

Provides context for this failure.

fn compat(self) -> Compat<Self>

where Self: Sized,

Wraps this failure in a compatibility wrapper that implements std::error::Error.

impl From<Context<ErrorKind>> for Error

fn from(inner: Context<ErrorKind>) -> Error

Converts to this type from the input type.

impl From<ErrorKind> for Error

fn from(kind: ErrorKind) -> Error

Converts to this type from the input type.
