Struct nostr_sdk::bitcoin::FeeRate

pub struct FeeRate(_);

Represents fee rate.

This is an integer newtype representing fee rate in sat/kwu. It provides protection against mixing up the types as well as basic formatting features.

Implementations

impl FeeRate

pub const ZERO: FeeRate = FeeRate(0)

0 sat/kwu.

Equivalent to MIN, may better express intent in some contexts.

pub const MIN: FeeRate = FeeRate(u64::min_value())

Minimum possible value (0 sat/kwu).

Equivalent to ZERO, may better express intent in some contexts.

pub const MAX: FeeRate = FeeRate(u64::max_value())

Maximum possible value.

pub const BROADCAST_MIN: FeeRate = FeeRate::from_sat_per_vb_unchecked(1)

Minimum fee rate required to broadcast a transaction.

The value matches the default Bitcoin Core policy at the time of library release.

pub const DUST: FeeRate = FeeRate::from_sat_per_vb_unchecked(3)

Fee rate used to compute dust amount.

pub const fn from_sat_per_kwu(sat_kwu: u64) -> FeeRate

Constructs FeeRate from satoshis per 1000 weight units.

pub fn from_sat_per_vb(sat_vb: u64) -> Option<FeeRate>

Constructs FeeRate from satoshis per virtual bytes.

Errors

Returns None on arithmetic overflow.

pub const fn from_sat_per_vb_unchecked(sat_vb: u64) -> FeeRate

Constructs FeeRate from satoshis per virtual bytes without overflow check.

pub const fn to_sat_per_kwu(self) -> u64

Returns raw fee rate.

Can be used instead of into() to avoid inference issues.

pub const fn to_sat_per_vb_floor(self) -> u64

Converts to sat/vB rounding down.

pub const fn to_sat_per_vb_ceil(self) -> u64

Converts to sat/vB rounding up.

pub fn checked_mul(self, rhs: u64) -> Option<FeeRate>

Checked multiplication.

Computes self * rhs returning None if overflow occurred.

pub fn checked_div(self, rhs: u64) -> Option<FeeRate>

Checked division.

Computes self / rhs returning None if rhs == 0.

impl Mul<FeeRate> for Weight

Computes ceiling so that fee computation is conservative.

type Output = Amount

The resulting type after applying the * operator.

fn mul(self, rhs: FeeRate) -> <Weight as Mul<FeeRate>>::Output

Performs the * operation.

impl Mul<Weight> for FeeRate

type Output = Amount

The resulting type after applying the * operator.

fn mul(self, rhs: Weight) -> <FeeRate as Mul<Weight>>::Output

Performs the * operation.

impl Ord for FeeRate

fn cmp(&self, other: &FeeRate) -> Ordering

This method returns an Ordering between self and other.
