Struct weave::Error
[−]
[src]
pub struct Error(pub ErrorKind, pub State);
The Error type.
This struct is made of three things:
ErrorKind
which is used to determine the type of the error.- a backtrace, generated when the error is created.
- an error chain, used for the implementation of
Error::cause()
.
Methods
impl Error
[src]
fn from_kind(kind: ErrorKind) -> Error
Constructs an error from a kind, and generates a backtrace.
fn with_chain<__E, __K>(error: __E, kind: __K) -> Self where
__E: Error + Send + 'static,
__K: Into<ErrorKind>,
__E: Error + Send + 'static,
__K: Into<ErrorKind>,
Constructs a chained error from another error and a kind, and generates a backtrace.
fn kind(&self) -> &ErrorKind
Returns the kind of the error.
fn iter(&self) -> ErrorChainIter
Iterates over the error chain.
fn backtrace(&self) -> Option<&Backtrace>
Returns the backtrace associated with this error.
Methods from Deref<Target = ErrorKind>
fn description(&self) -> &str
A string describing the error kind.
