Struct gstd::Reservation

pub struct Reservation { /* private fields */ }

Stores additional data along with ReservationId to track its state.

Implementations

impl Reservation

pub fn reserve(amount: u64, duration: u32) -> Result<Self>

Reserve the amount of gas for further usage.

duration is the block count within which the reserve must be used.

Refer to ReservationId for the more detailed description.

pub fn unreserve(self) -> Result<u64>

Unreserve unused gas from the reservation.

If successful, it returns the reserved amount of gas.

pub fn id(&self) -> ReservationId

ReservationId associated with current Reservation.

pub fn amount(&self) -> u64

Amount of gas stored inside this Reservation.

pub fn valid_until(&self) -> u32

Returns block number when this Reservation expires.
