Implementations

impl AggregationFunction

pub fn to_index(function_id: &Self) -> u8

pub fn from_index(index: u8) -> Result<Self>

pub fn operation( &self, values: &[U256], ctx: Option<FunctionContext>, ) -> Result<U256>

Trait Implementations

impl Clone for AggregationFunction

fn clone(&self) -> AggregationFunction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AggregationFunction

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AggregationFunction

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for AggregationFunction

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

Formats the value using the given formatter.

impl Distribution<AggregationFunction> for Standard

fn sample<R: Rng + ?Sized>(&self, rng: &mut R) -> AggregationFunction

Generate a random value of T, using rng as the source of randomness.

fn sample_iter<R>(self, rng: R) -> DistIter<Self, R, T>

where R: Rng, Self: Sized,

Create an iterator that generates random values of T, using rng as the source of randomness.

fn map<F, S>(self, func: F) -> DistMap<Self, F, T, S>

where F: Fn(T) -> S, Self: Sized,

Create a distribution of values of ‘S’ by mapping the output of Self through the closure F

impl FromStr for AggregationFunction

Get AggregationFunction from function id

type Err = Error

The associated error which can be returned from parsing.

fn from_str(function_id: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for AggregationFunction

fn eq(&self, other: &AggregationFunction) -> 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 Serialize for AggregationFunction

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for AggregationFunction
