Struct solana_evm_loader_program::scope::evm::secp256k1::rand::Error [−][src]
Error type of random number generators
This is a relatively simple error type, designed for compatibility with and
without the Rust std
library. It embeds a “kind” code, a message (static
string only), and an optional chained cause (std
only). The kind
and
msg
fields can be accessed directly; cause can be accessed via
std::error::Error::cause
or Error::take_cause
. Construction can only be
done via Error::new
or Error::with_cause
.
Fields
kind: ErrorKind
The error kind
msg: &'static str
The error message
Implementations
impl Error
[src]
pub fn new(kind: ErrorKind, msg: &'static str) -> Error
[src]
Create a new instance, with specified kind and a message.
pub fn with_cause<E>(kind: ErrorKind, msg: &'static str, cause: E) -> Error where
E: Into<Box<dyn Error + 'static + Send + Sync, Global>>,
[src]
E: Into<Box<dyn Error + 'static + Send + Sync, Global>>,
Create a new instance, with specified kind, message, and a chained cause.
Note: stdError
is an alias for std::error::Error
.
If not targetting std
(i.e. no_std
), this function is replaced by
another with the same prototype, except that there are no bounds on the
type E
(because both Box
and stdError
are unavailable), and the
cause
is ignored.
pub fn take_cause(
&mut self
) -> Option<Box<dyn Error + 'static + Send + Sync, Global>>
[src]
&mut self
) -> Option<Box<dyn Error + 'static + Send + Sync, Global>>
Take the cause, if any. This allows the embedded cause to be extracted.
This uses Option::take
, leaving self
with no cause.
