Struct FeeQuote 

pub struct FeeQuote {
    pub input: Amounts,
    pub output: Amounts,
    pub dust: Amounts,
}

Breakdown of the fee finalizing a transaction would incur, as computed by Client::fee_quote (a dry-run of the same balancing the real submission performs).

This is module-agnostic: the explicit inputs/outputs are described by the FeeQuoteRequest from whichever module is quoting (mint, lightning, wallet, …) and the change is generated by the primary module. The quote is point-in-time: it depends on the client’s current inventory and can move as funds change.

Each field is a multi-unit Amounts, since the quoted operation may span several units. The total fee is the sum of the breakdown fields, available via FeeQuote::total.

Fields

input: Amounts

Federation fees charged on the spent (input) items — both the transaction’s explicit inputs and any inputs the primary module pulls in to balance it.

output: Amounts

Federation fees charged on the created (output) items — both the transaction’s explicit outputs and the change minted to balance it.

dust: Amounts

Sub-denomination remainder that cannot form an output and is lost.

Implementations

impl FeeQuote

pub const ZERO: Self

A zero fee, for operations that incur no cost at all — e.g. an ecash send served entirely from existing exact-change notes, which submits no transaction.

pub fn total(&self) -> Amounts

Total fee per unit: everything the gross input value does not become a net wallet gain. Equal to input + output + dust.

Trait Implementations

impl Clone for FeeQuote

fn clone(&self) -> FeeQuote

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FeeQuote

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for FeeQuote

fn eq(&self, other: &FeeQuote) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
