Struct FeeRate 

pub struct FeeRate {
    per_weight: u64,
    mask: u64,
}

A struct containing a fee rate.

The fee rate is defined as a per-weight cost, along with a mask for rounding purposes.

Fields

per_weight: u64

The fee per-weight of the transaction.

mask: u64

The mask to round with.

Implementations

impl FeeRate

pub fn new(per_weight: u64, mask: u64) -> Option<FeeRate>

Construct a new fee rate.

Returns None if the fee rate is invalid.

pub fn write(&self, w: &mut impl Write) -> Result<()>

Write the FeeRate.

This is not a Monero protocol defined struct, and this is accordingly not a Monero protocol defined serialization. This may run in time variable to its value.

pub fn serialize(&self) -> Vec<u8>

Serialize the FeeRate to a Vec<u8>.

This is not a Monero protocol defined struct, and this is accordingly not a Monero protocol defined serialization. This may run in time variable to its value.

pub fn per_weight(&self) -> u64

The fee to pay per weight.

pub fn read(r: &mut impl Read) -> Result<FeeRate>

Read a FeeRate.

This is not a Monero protocol defined struct, and this is accordingly not a Monero protocol defined serialization. This may run in time variable to its value.

pub fn calculate_fee_from_weight(&self, weight: usize) -> u64

Calculate the fee to use from the weight.

This function may panic upon overflow.

pub fn calculate_weight_from_fee(&self, fee: u64) -> Option<usize>

Calculate the weight from the fee.

Returns None if the weight would not fit within a usize.

Trait Implementations

impl Clone for FeeRate

fn clone(&self) -> FeeRate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FeeRate

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

Formats the value using the given formatter.

impl Eq for FeeRate

#[doc(hidden)] fn assert_receiver_is_total_eq(&self)

impl PartialEq for FeeRate

fn eq(&self, other: &FeeRate) -> 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.

impl Zeroize for FeeRate

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.

impl Copy for FeeRate

impl StructuralPartialEq for FeeRate

impl TrivialClone for FeeRate
