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

pub struct RandomBytesError { /* fields omitted */ }

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

#[must_use]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");

#[must_use]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");
