u256_from_u32_array

Converts an array of 8 u32 values into a single u256 value.

This function treats the input array as a sequence of 32-bit words, where the first element of the array represents the most significant 32 bits and the last element represents the least significant 32 bits. The resulting u256 value is constructed by combining these words in big-endian order.

Arguments

• arr - An array of 8 u32 values to be converted into a u256.

Returns

• A u256 value representing the combined value of the input array.

Example

let arr: [u32; 8] = [0x1, 0x2, 0x3, 0x4, 0x5, 0x6, 0x7, 0x8];
let result: u256 = u256_from_u32_array(arr);
// `result` will now hold the value:
// 0x00000001_00000002_00000003_00000004_00000005_00000006_00000007_00000008
