[][src]Struct rand::Error

pub struct Error { /* fields omitted */ }

Error type of random number generators

In order to be compatible with std and no_std, this type has two possible implementations: with std a boxed Error trait object is stored, while with no_std we merely store an error code.

Methods

impl Error[src]

pub fn new<E>(err: E) -> Error where
    E: Into<Box<dyn Error + 'static + Send + Sync>>, 
[src]

Construct from any type supporting std::error::Error

Available only when configured with std.

See also From<NonZeroU32>, which is available with and without std.

pub fn inner(&self) -> &(dyn Error + 'static + Send + Sync)[src]

Reference the inner error (std only)

When configured with std, this is a trivial operation and never panics. Without std, this method is simply unavailable.

pub fn take_inner(self) -> Box<dyn Error + 'static + Send + Sync>[src]

Unwrap the inner error (std only)

When configured with std, this is a trivial operation and never panics. Without std, this method is simply unavailable.

pub fn code(&self) -> Option<NonZeroU32>[src]

Retrieve the error code, if any.

If this Error was constructed via From<NonZeroU32>, then this method will return this NonZeroU32 code (for no_std this is always the case). Otherwise, this method will return None.
