Struct Hash256 

pub struct Hash256(pub [u8; 32]);

A 256-bit hash (32 bytes), serialized as 0x-prefixed hex string.

On deserialization, both 0x-prefixed and non-prefixed hex strings are accepted. No domain-specific validation is performed — the only check is hex format and 32-byte length.

Tuple Fields

0: [u8; 32]
