[−][src]Struct signature::Error
Signature errors
Methods
impl Error
[src]
pub fn new() -> Self
[src]
Create a new error with no cause
pub fn from_cause<E>(cause: E) -> Self where
E: Into<Box<dyn Error>>,
[src]
E: Into<Box<dyn Error>>,
Create a new error with an associated cause.
NOTE: The "cause" should NOT be used to propagate cryptographic errors e.g. signature parsing or verification errors.
The intended use cases are for propagating errors related to external signers, e.g. communication/authentication errors with HSMs, KMS, etc.
pub fn cause(&self) -> Option<&dyn Error>
[src]
Borrow the error's underlying cause (if available)
pub fn into_cause(self) -> Box<dyn Error>
[src]
Extract the underlying cause of this error.
Panics if the error does not have a cause.
pub fn downcast<T>(self) -> Result<Box<T>, Box<dyn Error>> where
T: Error + 'static,
[src]
T: Error + 'static,
Attempt to downcast this error's cause into a concrete type
pub fn downcast_ref<T>(&self) -> Option<&T> where
T: Error + 'static,
[src]
T: Error + 'static,
Attempt to downcast a reference to this error's cause into a concrete type
