Struct odra_core :: callstack :: Callstack Copy item path

impl Callstack

pub fn first(&self) -> CallstackElement

Returns the first (bottom most) callstack element.

pub fn pop(&mut self) -> Option<CallstackElement>

Returns the current callstack element and removes it from the callstack.

pub fn push(&mut self, element: CallstackElement)

Pushes a new callstack element onto the callstack.

pub fn attached_value(&self) -> U512

Returns the attached value.

If the current element is a contract call, the attached value is the amount of tokens attached to the contract call. If the current element is an account, the attached value is zero.

pub fn attach_value(&mut self, amount: U512)

Attaches the given amount of tokens to the current contract call.

If the current element is not a contract call, this method does nothing.

pub fn current(&self) -> &CallstackElement

Returns the current callstack element.

pub fn previous(&self) -> &CallstackElement

Returns the previous (second) callstack element.

pub fn size(&self) -> usize

Returns the size of the callstack.

pub fn is_empty(&self) -> bool

Returns true if the callstack is empty.
