Enum Interval 

pub enum Interval {
    Minute,
    Hour,
    Day,
    Week,
}

Candle aggregation interval.

Represents the time granularity of OHLCV candles used for backtesting, data collection, and strategy execution.

Variants

Minute

1-minute candles.

Hour

1-hour candles.

Day

1-day (daily) candles.

Week

1-week (weekly) candles.

Implementations

impl Interval

pub fn as_str(&self) -> &'static str

Canonical short string representation.

pub fn periods_per_year(&self, is_crypto: bool) -> u32

Number of periods per year for annualization (#1530).

Crypto markets trade 24/7 (365 days, 8760 hours). Traditional equity markets trade ~252 days/year, ~6.5 hours/day.

Used by Sharpe, Sortino, annualized return, CAGR calculations.

pub fn lower_intervals(&self) -> &'static [Interval]

Returns lower intervals that can be aggregated into this one, ordered by preference.

For example, Day returns [Hour, Minute] — try hourly first, then minute. Minute returns [] — nothing can be aggregated into minute candles.

Trait Implementations

impl Clone for Interval

fn clone(&self) -> Interval

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Interval

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Interval

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for Interval

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

Formats the value using the given formatter.

impl FromStr for Interval

type Err = IntervalError

The associated error which can be returned from parsing.

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

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

impl Hash for Interval

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Interval

fn eq(&self, other: &Interval) -> 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 Interval

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

Serialize this value into the given Serde serializer.

impl Copy for Interval

impl Eq for Interval

impl StructuralPartialEq for Interval
