Macro soroban_sdk::bigint

macro_rules! bigint {
    ($env:expr $(,)?) => { ... };
    ($env:expr, [$($x:expr),+ $(,)?] $(,)?) => { ... };

Create a BigInt with an integer, hex, bits, or an array.

The first argument in the list must be a reference to an Env.

The second argument can be an integer literal of unbounded size in any form: base10, hex, etc, or an u8 array.

Examples

Create a BigInt with an integer:

use soroban_sdk::{Env, bigint};

let env = Env::default();
let big = bigint!(&env, -5);
assert_eq!(big.to_i64(), -5i64);

Create a BigInt with hex:

use soroban_sdk::{Env, bigint};

let env = Env::default();
let big = bigint!(&env, 0xfded3f55dec47250a52a8c0bb7038e72fa6ffaae33562f77cd2b629ef7fd424d);
assert_eq!(big.bits(), 256);

Create a BigInt with an array:

use soroban_sdk::{Env, bigint};

let env = Env::default();
let big = bigint!(&env, [2, 0]);
assert_eq!(big, 512);
