Struct rand::rngs::adapter::ReadRng[][src]

pub struct ReadRng<R> { /* fields omitted */ }
👎 Deprecated since 0.8.4:

removal due to lack of usage

This is supported on crate feature std only.
Expand description

An RNG that reads random bytes straight from any type supporting std::io::Read, for example files.

This will work best with an infinite reader, but that is not required.

This can be used with /dev/urandom on Unix but it is recommended to use OsRng instead.

Panics

ReadRng uses std::io::Read::read_exact, which retries on interrupts. All other errors from the underlying reader, including when it does not have enough data, will only be reported through try_fill_bytes. The other RngCore methods will panic in case of an error.
