Trait Implementations

impl From<ProtoErrorKind> for ProtoError

fn from(kind: ProtoErrorKind) -> ProtoError

Performs the conversion.

impl PartialEq<ProtoErrorKind> for ProtoErrorKind

fn eq(&self, other: &ProtoErrorKind) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ProtoErrorKind) -> bool

This method tests for !=.

impl Clone for ProtoErrorKind

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Eq for ProtoErrorKind

impl Display for ProtoErrorKind

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

Formats the value using the given formatter.

impl Debug for ProtoErrorKind

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

Formats the value using the given formatter.

impl Fail for ProtoErrorKind

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

Returns the "name" of the error.

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

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 context<D>(self, context: D) -> Context<D> where
    D: Display + Send + Sync + 'static, 

Provides context for this failure.

fn compat(self) -> Compat<Self>

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