Struct artichoke_backend::extn::stdlib::securerandom::RandomBytesError

pub struct RandomBytesError { /* private fields */ }

Error that indicates the underlying source of randomness failed to generate the requested random bytes.

This error is typically returned by the operating system.

Implementations

impl RandomBytesError

pub const fn new() -> RandomBytesError

Construct a new, default random bytes error.

Examples

const ERR: RandomBytesError = RandomBytesError::new();
assert_eq!(ERR.message(), "OS Error: Failed to generate random bytes");

pub const fn message(self) -> &'static str

Retrieve the exception message associated with this random bytes error.

Examples

let err = RandomBytesError::new();
assert_eq!(err.message(), "OS Error: Failed to generate random bytes");

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
