pub struct FmtError(pub ErrorKind, _);Expand description
The Error type.
This tuple struct is made of two elements:
- an
ErrorKindwhich is used to determine the type of the error. - An internal
State, not meant for direct use outside oferror_chaininternals, containing:- a backtrace, generated when the error is created.
- an error chain, used for the implementation of
Error::cause().
Tuple Fields§
§0: ErrorKindThe kind of the error.
Implementations§
source§impl Error
impl Error
sourcepub fn from_kind(kind: ErrorKind) -> Error
pub fn from_kind(kind: ErrorKind) -> Error
Constructs an error from a kind, and generates a backtrace.
sourcepub fn with_chain<E, K>(error: E, kind: K) -> Errorwhere
E: Error + Send + 'static,
K: Into<ErrorKind>,
pub fn with_chain<E, K>(error: E, kind: K) -> Errorwhere
E: Error + Send + 'static,
K: Into<ErrorKind>,
Constructs a chained error from another error and a kind, and generates a backtrace.
sourcepub fn iter(&self) -> ErrorChainIter<'_>
pub fn iter(&self) -> ErrorChainIter<'_>
Iterates over the error chain.
Methods from Deref<Target = ErrorKind>§
sourcepub fn description(&self) -> &str
pub fn description(&self) -> &str
A string describing the error kind.
