Struct ResolvedGasSponsor 

Source 
pub struct ResolvedGasSponsor {
    pub identity_id: Identifier,
    pub balance: Credits,
    pub strict: bool,
}
Expand description

The contract owner a batch asks to pay its gas, with the balance the batch transformer read for them. Resolved from protocol version 14, and only when the contract owner is not the batch’s own signer: fee validation checks the fee against this balance, and execution charges this identity instead of the signer when it covers the fee. A batch that failed validation is never sponsored, whatever it asked for: its signer pays for the work that ran.

Fields§

§identity_id: Identifier

The contract owner

§balance: Credits

Their balance when the batch was transformed

§strict: bool

Whether the batch insists on the contract owner paying (GasFeesPaidBy::ContractOwner): then a balance that does not cover the fee refuses the batch unpaid. Otherwise (PreferContractOwner) the signer pays instead.

Implementations§

Source§

impl ResolvedGasSponsor

Source

pub fn covers(&self, required_balance: Credits) -> bool

Whether the contract owner pays: their balance covers the whole fee. Fee validation and execution both decide by this, on the same estimated fee, so they always agree.
