Struct SlotCalculator

pub struct SlotCalculator { /* private fields */ }

A slot calculator, which can calculate the slot number for a given timestamp.

Implementations

impl SlotCalculator

pub const fn new( start_timestamp: u64, slot_offset: u64, slot_duration: u64, ) -> Self

Creates a new slot calculator.

pub const fn holesky() -> Self

Creates a new slot calculator for Holesky.

pub const fn pecorino_host() -> Self

Creates a new slot calculator for Pecorino host network.

pub const fn mainnet() -> Self

Creates a new slot calculator for Ethereum mainnet.

pub const fn calculate_slot(&self, timestamp: u64) -> u64

Calculates the slot for a given timestamp. This only works for timestamps that are GEQ to the chain’s start_timestamp.

pub const fn calculate_timepoint_within_slot(&self, timestamp: u64) -> u64

Calculates how many seconds into the block window for a given timestamp.

pub const fn calculate_slot_window(&self, slot_number: u64) -> (u64, u64)

Calculates the start and end timestamps for a given slot

pub fn current_slot(&self) -> u64

The current slot number.

pub fn current_timepoint_within_slot(&self) -> u64

The current number of seconds into the block window.

pub const fn start_timestamp(&self) -> u64

The timestamp of the first PoS block in the chain.

pub const fn slot_offset(&self) -> u64

The slot number of the first PoS block in the chain.

pub const fn slot_duration(&self) -> u64

The slot duration, usually 12 seconds.

Trait Implementations

impl Clone for SlotCalculator

fn clone(&self) -> SlotCalculator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SlotCalculator

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SlotCalculator

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromEnv for SlotCalculator

type Error = SlotCalculatorEnvError

Error type produced when loading from the environment.

fn inventory() -> Vec<&'static EnvItemInfo>

Get the required environment variable names for this type.

fn from_env() -> Result<Self, FromEnvErr<Self::Error>>

Load from the environment.

fn check_inventory() -> Result<(), Vec<&'static EnvItemInfo>>

Get a list of missing environment variables.

impl PartialEq for SlotCalculator

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

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

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

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