Struct fuel_tx::TransactionFee

pub struct TransactionFee { /* private fields */ }

Implementations

impl TransactionFee

pub const fn new(bytes: Word, total: Word) -> Self

pub const fn min(&self) -> Word

Minimum fee value to pay for the metered bytes

pub const fn total(&self) -> Word

Maximum fee value composed of metered bytes cost + tx gas limit, with price factor correction

pub const fn into_inner(self) -> (Word, Word)

Convert into a tuple containing the inner min & total fee values

pub fn checked_deduct_total(&self, balance: Word) -> Option<Word>

Attempt to subtract the maximum fee value from a given balance

Will return None if arithmetic overflow occurs.

pub fn checked_from_values(
    params: &ConsensusParameters,
    metered_bytes: Word,
    gas_limit: Word,
    gas_price: Word
) -> Option<Self>

Attempt to create a transaction fee from parameters and value arguments

Will return None if arithmetic overflow occurs.

pub fn gas_refund_value(
    params: &ConsensusParameters,
    gas: Word,
    price: Word
) -> Option<Word>

Attempt to calculate a gas as asset value, using the price factor defined in the consensus parameters.

Will return None if overflow occurs

pub fn checked_from_tx<T>(params: &ConsensusParameters, tx: T) -> Option<Self> where
    T: Borrow<Transaction>, 

Attempt to create a transaction fee from parameters and transaction internals

Will return None if arithmetic overflow occurs.
