Struct nannou_core::rand::rngs::adapter::ReadRng [−][src]
pub struct ReadRng<R> { /* fields omitted */ }
removal due to lack of usage
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.

Convert into T. The resulting color might be invalid in its color space Read more
Convert into T, returning ok if the color is inside of its defined range,
otherwise an OutOfBounds
error is returned which contains the unclamped color. Read more

Return a bool with a probability p

Return a bool with a probability of numerator/denominator
of being
true. I.e. gen_ratio(2, 3)
has chance of 2 in 3, or about 67%, of
returning true. If numerator == denominator
, then the returned value
is guaranteed to be true
. If numerator == 0
, then the returned
value is guaranteed to be false
. Read more
