Struct TimeRangeSelection 

pub struct TimeRangeSelection {
    pub selector: i32,
    pub start_ms: Option<u64>,
    pub grid: Option<Grid>,
}

Operand of an IN_TIME_RANGE where clause: which window of a timeRange grid the query selects. Typed rather than riding DocumentFieldValue — the selection is not a field value, and a structured message keeps the selector an enum instead of a magic string.

The relative selectors are resolved server-side: NEWEST is the freshest started window (largest grid start <= block time; the latest partial slice of history), OLDEST the oldest window still active at block time (a near-full trailing window of ~range — best for “trending over the last window”). The proof verifier re-derives the same window from the quorum-signed response metadata time, so neither side trusts the other’s clock.

BY_START names a window absolutely — any window, current or historic — by its start. start_ms is then required and must lie on the grid (start_ms == phase + k * step, in milliseconds); an unaligned start is rejected rather than snapped. A window with no documents (including one that has not started yet) is a provable empty answer, not an error. The relative selectors must NOT carry start_ms — one wire spelling per meaning.

Fields

selector: i32

start_ms: Option<u64>

BY_START only: the selected window’s start, as a millisecond timestamp on the grid (see the message docstring). Rejected on the relative selectors.

grid: Option<Grid>

Implementations

impl TimeRangeSelection

pub fn selector(&self) -> Selector

Returns the enum value of selector, or the default if the field is set to an invalid enum value.

pub fn set_selector(&mut self, value: Selector)

Sets selector to the provided enum value.

pub fn start_ms(&self) -> u64

Returns the value of start_ms, or the default value if start_ms is unset.

Trait Implementations

impl Clone for TimeRangeSelection

fn clone(&self) -> TimeRangeSelection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TimeRangeSelection

impl Debug for TimeRangeSelection

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

Formats the value using the given formatter.

impl Default for TimeRangeSelection

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TimeRangeSelection

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for TimeRangeSelection

impl Hash for TimeRangeSelection

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 Message for TimeRangeSelection

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

impl Mockable for TimeRangeSelection

fn mock_serialize(&self) -> Option<Vec<u8>>

impl PartialEq for TimeRangeSelection

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
