Struct RouterFees 

pub struct RouterFees { /* private fields */ }

Router fee configuration: precision scale, default rates, and per-client overrides.

Mirrors the on-chain FeeCalculator state. Rates are in fee units where max_fee_units represents 100%.

Implementations

impl RouterFees

pub fn new( max_fee_units: u64, default_fee_on_output: u32, default_fee_on_client_fee: u32, custom_fees: HashMap<Bytes, (u32, u32)>, ) -> Self

Creates a fee configuration from on-chain values. custom_fees maps a client to its resolved (fee_on_output, fee_on_client_fee) pair in fee units.

pub fn fallback() -> Self

Conservative fallback used until the on-chain FeeCalculator has been read, and whenever a fetch fails: a 0.1 bps router fee on output, no fee on client fees, and no per-client overrides. Lets the encoder always produce a transaction rather than failing.

pub fn max_fee_units(&self) -> u64

Fee units representing 100% (the contract’s MAX_FEE_BPS).

pub fn fees_for(&self, client: &Bytes) -> FeeRates

Resolves the effective fee rates for client: the per-client pair when present, otherwise the defaults. The fetcher has already applied FeeCalculator._getFeeInfo’s override-or-default logic per field, so this is a plain lookup. The contract’s precision scale travels with the rates.

pub fn custom_client_count(&self) -> usize

Number of clients with at least one custom fee override.
