Struct Fee 

pub struct Fee {
    pub amount: Vec<Coin>,
    pub gas_limit: u64,
    pub payer: Option<AccountId>,
    pub granter: Option<AccountId>,
}

Fee includes the amount of coins paid in fees and the maximum gas to be used by the transaction.

The ratio yields an effective “gasprice”, which must be above some minimum to be accepted into the mempool.

Fields

amount: Vec<Coin>

Amount of coins to be paid as a fee.

gas_limit: u64

Maximum gas that can be used in transaction processing before an out of gas error occurs.

payer: Option<AccountId>

Payer: if None, the first signer is responsible for paying the fees.

If Some, the specified account must pay the fees. The payer must be a tx signer (and thus have signed this field in AuthInfo).

Setting this field does not change the ordering of required signers for the transaction.

granter: Option<AccountId>

Granter: if Some, the fee payer (either the first signer or the value of the payer field) requests that a fee grant be used to pay fees instead of the fee payer’s own balance.

If an appropriate fee grant does not exist or the chain does not support fee grants, this will fail.

Implementations

impl Fee
