Struct NativeToken 

#[repr(C)]
pub struct NativeToken;

Implementations

impl NativeToken

pub fn initialize( env: &mut Env<'_>, (own_address, own_balance): (&Address, &mut MaybeData<'_, Slot>), max_issuance: &Balance, ) -> Result<Self, ContractError>

Initialize native token on a shard with max issuance allowed by this shard.

Block rewards will be implemented using transfers from native token’s balance.

pub fn balance(target: &MaybeData<'_, Slot>) -> Balance

pub fn transfer( env: &mut Env<'_>, (from_address, from): (&Address, &mut MaybeData<'_, Slot>), to: &mut MaybeData<'_, Slot>, amount: &Balance, ) -> Result<(), ContractError>

Like [Self::try_from_bytes()], but returns an exclusive reference.

final fn try_from_bytes_mut_exact(bytes: &mut [u8]) -> Option<&mut Self>

Like [Self::try_from_bytes_mut()], but returns None if there are more bytes than the value

final fn from_bytes(bytes: &[u8]) -> Option<(&Self, &[u8])>

where Self: AnyBitPattern,
