Struct Address

pub struct Address(/* private fields */);

Expand description

An Address is just a H256 with a different name. Has a different ABI name than H256.

Note: we are currently using ManagedAddress in contracts. While this also works, its use in contracts is discouraged.

Implementations§

impl Address

pub const fn new(bytes: [u8; 32]) -> Address
