# Struct rand::distributions::exponential::Exp1 [−] [src]

    pub struct Exp1(pub f64);

A wrapper around an `f64` to generate Exp(1) random numbers.

See `Exp` for the general exponential distribution.

Implemented via the ZIGNOR variant[1] of the Ziggurat method. The exact description in the paper was adjusted to use tables for the exponential distribution rather than normal.

# Example

    use rand::distributions::exponential::Exp1;

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
