Struct rand::Error

pub struct Error { /* fields omitted */ }

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).

Methods

impl Error

pub fn new(kind: ErrorKind, msg: &'static str) -> Self

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

pub fn with_cause<E>(kind: ErrorKind, msg: &'static str, cause: E) -> Self where
    E: Into<Box<stdError + Send + Sync>>, 

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 kind(&self) -> ErrorKind

Get the error kind

pub fn msg(&self) -> &'static str

Get the error message
