impl Value
pub fn copy(&self) -> Result<Self, ExecutionError>
Sourcepub fn read_ref(self) -> Result<Self, ExecutionError>
pub fn read_ref(self) -> Result<Self, ExecutionError>
Read the value, giving an invariant violation if the value is not a reference
Sourcepub fn cast<V>(self) -> Result<V, ExecutionError>where
VMValue: VMValueCast<V>,
pub fn cast<V>(self) -> Result<V, ExecutionError>where
VMValue: VMValueCast<V>,
This function will invariant violation on an invalid cast

Sourcepub fn coin(id: ObjectID, amount: u64) -> Self
pub fn coin(id: ObjectID, amount: u64) -> Self

Sourcepub fn coin_ref_subtract_balance(
self,
amount: u64,
) -> Result<(), ExecutionError>
pub fn coin_ref_subtract_balance( self, amount: u64, ) -> Result<(), ExecutionError>
The coin value MUST be checked before calling this function, if amount
is greater than
the value of the coin, it will return an invariant violation.
Sourcepub fn coin_ref_add_balance(self, amount: u64) -> Result<(), ExecutionError>
pub fn coin_ref_add_balance(self, amount: u64) -> Result<(), ExecutionError>
The coin max value MUST be checked before calling this function, if amount
plus the current
balance is greater than u64::MAX
, it will return an invariant violation.
