Struct grin_core::core::transaction::FeeFields

pub struct FeeFields(/* private fields */);

Fee fields as in fix-fees RFC: { future_use: 20, fee_shift: 4, fee: 40 }

Implementations

impl FeeFields

pub const FEE_SHIFT_BITS: u32 = 4u32

Fee shifts are limited to 4 bits

pub const FEE_SHIFT_MASK: u64 = 15u64

Used to extract fee_shift field

pub fn zero() -> Self

Create a zero FeeFields with 0 fee and 0 fee_shift

pub fn new(fee_shift: u64, fee: u64) -> Result<Self, Error>

Create a new FeeFields from the provided shift and fee Checks both are valid (in range)

pub fn fee_shift(&self) -> u8

Extract fee_shift field

pub fn fee(&self) -> u64

Extract fee field

pub fn as_opt(&self) -> Option<Self>

Turn a zero FeeField into a None, any other value into a Some. We need this because a zero FeeField cannot be deserialized.

pub fn is_zero(&self) -> bool

Check if the FeeFields is set to zero

Trait Implementations

impl Clone for FeeFields

fn clone(&self) -> FeeFields

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FeeFields

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FeeFields

fn deserialize<D>(deserializer: D) -> Result<FeeFields, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for FeeFields

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

Formats the value using the given formatter.

impl From<FeeFields> for u64

fn from(fee_fields: FeeFields) -> Self

Converts to this type from the input type.

impl From<u32> for FeeFields

Conversion from a 32-bit fee to a FeeFields with 0 fee_shift For use exclusively in tests with constant fees

fn from(fee: u32) -> Self

Converts to this type from the input type.

impl PartialEq for FeeFields

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Readable for FeeFields

fn read<R: Reader>(reader: &mut R) -> Result<Self, Error>

Reads the data necessary to this Readable from the provided reader

impl Serialize for FeeFields

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<u64> for FeeFields

Conversion from a valid fee to a FeeFields with 0 fee_shift The valid fee range is 1..FEE_MASK

type Error = Error

The type returned in the event of a conversion error.

fn try_from(fee: u64) -> Result<Self, Self::Error>

Performs the conversion.

impl Writeable for FeeFields

fn write<W: Writer>(&self, writer: &mut W) -> Result<(), Error>

Write the data held by this Writeable to the provided writer

impl Copy for FeeFields

impl DefaultHashable for FeeFields

impl StructuralPartialEq for FeeFields
