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.

Methods

impl Error
[src]

Create a new instance, with specified kind and a message.

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.

Take the cause, if any. This allows the embedded cause to be extracted. This uses Option::take, leaving self with no cause.
