Enum DurationOfPart 

pub enum DurationOfPart {
    Auto,
    LimitDuration {
        duration: u32,
    },
}

Duration constraint for each individual TWAP part.

• DurationOfPart::Auto encodes span = 0 on-chain, meaning each part is valid for the entire part_duration window.
• DurationOfPart::LimitDuration encodes span = duration, restricting each part to a shorter window within the overall interval.

Variants

Auto

Each part is valid for the full part_duration window (default).

LimitDuration

Each part is valid only for duration seconds within the window.

Fields

duration: u32

Active window for the part, in seconds. Must be ≤ part_duration.

Implementations

impl DurationOfPart

pub const fn duration(self) -> Option<u32>

Return the limit duration in seconds, or None for Auto.

pub const fn is_auto(self) -> bool

Returns true if the part spans the full part_duration window.

pub const fn limit(duration: u32) -> Self

Construct a LimitDuration variant.

use cow_composable::DurationOfPart;

let d = DurationOfPart::limit(1_800);
assert!(!d.is_auto());
assert_eq!(d.duration(), Some(1_800));

pub const fn is_limit_duration(self) -> bool

Returns true if this is a LimitDuration variant.

use cow_composable::DurationOfPart;

assert!(DurationOfPart::limit(600).is_limit_duration());
assert!(!DurationOfPart::Auto.is_limit_duration());

Trait Implementations

impl Clone for DurationOfPart

fn clone(&self) -> DurationOfPart

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DurationOfPart

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

Formats the value using the given formatter.

impl Default for DurationOfPart

fn default() -> DurationOfPart

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DurationOfPart

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DurationOfPart

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

Formats the value using the given formatter.

impl From<Option<u32>> for DurationOfPart

fn from(d: Option<u32>) -> Self

Convert an optional duration to a DurationOfPart.

Some(d) maps to DurationOfPart::LimitDuration; None maps to DurationOfPart::Auto.

impl PartialEq for DurationOfPart

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
