Enum TimeRangeSelector 

pub enum TimeRangeSelector {
    Newest,
    Oldest,
}

Which active time range a TOP(timeRange(...)) selection resolves to, when the index’s ranges overlap (range > step). Time-range queries are a v1-only feature; the v0 query surface is unaffected.

Variants

Newest

The freshest started range (largest start ≤ now). Covers the latest partial slice (0..step of history).

Oldest

The oldest range still active at now. Covers a near-full trailing window of ~range of history. Best for “trending over the last window”.

Implementations

impl TimeRangeSelector

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

The selector’s wire spelling — the IN_TIME_RANGE clause’s operand on the v1 getDocuments wire. The single source of truth for the string form: the SDK encoder, the drive-abci decoder and the wasm-sdk JSON parser all go through these two functions (and the serde derive above is renamed to match), so the spellings cannot drift apart.

pub fn from_string(value: &str) -> Option<Self>

Parses the wire spelling. Returns None for anything but the exact strings Self::as_str produces.

Trait Implementations

impl Clone for TimeRangeSelector

fn clone(&self) -> TimeRangeSelector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TimeRangeSelector

impl Debug for TimeRangeSelector

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TimeRangeSelector

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for TimeRangeSelector

impl PartialEq for TimeRangeSelector

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
