# Trait num_bigint::RandBigInt [−] [src]

    pub trait RandBigInt {
        fn gen_biguint(&mut self, bit_size: usize) -> BigUint;
        fn gen_bigint(&mut self, bit_size: usize) -> BigInt;
        fn gen_biguint_below(&mut self, bound: &BigUint) -> BigUint;
        fn gen_biguint_range(
            &mut self,
            lbound: &BigUint,
            ubound: &BigUint
        ) -> BigUint;
        fn gen_bigint_range(&mut self, lbound: &BigInt, ubound: &BigInt) -> BigInt;
    }

## Required Methods

### `fn gen_biguint(&mut self, bit_size: usize) -> BigUint`

Generate a random `BigUint` of the given bit size.

### `fn gen_bigint(&mut self, bit_size: usize) -> BigInt`

Generate a random BigInt of the given bit size.

### `fn gen_biguint_below(&mut self, bound: &BigUint) -> BigUint`

Generate a random `BigUint` less than the given bound. Fails when the bound is zero.

### `fn gen_biguint_range(&mut self, lbound: &BigUint, ubound: &BigUint) -> BigUint`

Generate a random `BigUint` within the given range. The lower bound is inclusive; the upper bound is exclusive. Fails when the upper bound is not greater than the lower bound.

### `fn gen_bigint_range(&mut self, lbound: &BigInt, ubound: &BigInt) -> BigInt`

Generate a random `BigInt` within the given range. The lower bound is inclusive; the upper bound is exclusive. Fails when the upper bound is not greater than the lower bound.

## 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`)
