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

    pub trait ToBigInt {
        fn to_bigint(&self) -> Option<BigInt>;
    }

A generic trait for converting a value to a `BigInt`. This may return `None` when converting from `f32` or `f64`, and will always succeed when converting from any integer or unsigned primitive, or `BigUint`.

## Required methods

### `fn to_bigint(&self) -> Option<BigInt>`

Converts the value of `self` to a `BigInt`.

## 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`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
