Struct SortBuilder 

pub struct SortBuilder { /* private fields */ }

Builds the sort array, one fluent verb per concern — each absorbing its own optionality so a request maps straight through with no per-field if let.

by/near/tiebreak/or_default dedup by sort key (first wins), so a field added twice — or an explicit sort that a tiebreak/default would repeat — appears once; raw is exempt. or_default only contributes when the builder would otherwise be empty.

use flusso_query::{SortBuilder, SortOrder, OrderBy};
let sorts = SortBuilder::new()
    .score_if(true)
    .by(count(), SortOrder::Desc)
    .by(keyword("city"), None::<OrderBy>)   // skipped
    .tiebreak(keyword("id"))
    .build();
assert_eq!(sorts.len(), 3);                 // _score, orderCount, id

Implementations

impl SortBuilder

pub fn new() -> Self

An empty builder.

pub fn by<H: Sortable>(self, handle: H, dir: impl Into<MaybeOrderBy>) -> Self

Sort by a field. dir accepts a SortOrder, an OrderBy, or an Option of either (a None skips the field) — so a request’s Option<dir> flows straight in. Nesting-aware: a field inside nested arrays renders the right nested chain from its scope.

pub fn near<S>( self, handle: Geo<S>, center: impl Into<Option<GeoPoint>>, ) -> Self

Sort by distance from center (_geo_distance, nearest first). A None center skips it. Pass a unit / script geo sort through raw.

pub fn score(self) -> Self

Sort by relevance _score (descending).

pub fn score_if(self, cond: bool) -> Self

Sort by _score only when cond holds (e.g. a free-text query is present).

pub fn raw(self, sort: impl Into<Option<Sort>>) -> Self

Append a pre-built Sort verbatim — the escape hatch for sorts the typed verbs don’t cover (_script, a geo sort with options). A None adds nothing. Not deduped.

pub fn tiebreak<H: Sortable>(self, handle: H) -> Self

A stable final sort key (ascending) — append a unique field so equal leading keys still page deterministically.

pub fn or_default(self, sort: impl Into<Sort>) -> Self

A fallback used only if nothing else lands in the builder.

pub fn build(self) -> Vec<Sort>

Finish: the sort array (the fallback, if set, when otherwise empty).

Trait Implementations

impl Debug for SortBuilder

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

Formats the value using the given formatter.

impl Default for SortBuilder

fn default() -> SortBuilder

Returns the “default value” for a type.

impl IntoIterator for SortBuilder

type Item = Sort

The type of the elements being iterated over.

type IntoIter = IntoIter<Sort>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
