C4QueryEnumerator

Struct C4QueryEnumerator 

Source
#[repr(C)]
pub struct C4QueryEnumerator { pub columns: FLArrayIterator, pub missingColumns: u64, pub fullTextMatchCount: u32, pub fullTextMatches: *const C4FullTextMatch, }
Expand description

A query result enumerator. Created by c4db_query. Must be freed with c4queryenum_release. The fields of this struct represent the current matched index row, and are valid until the next call to c4queryenum_next or c4queryenum_release.

Fields§

§columns: FLArrayIterator

The columns of this result, in the same order as in the query’s WHAT clause.

§missingColumns: u64

A bitmap where a 1 bit represents a column whose value is MISSING. This is how you tell a missing property value from a value that’s JSON ‘null’, since the value in the columns array will be a Fleece null either way.

§fullTextMatchCount: u32

The number of full-text matches (i.e. the number of items in fullTextMatches)

§fullTextMatches: *const C4FullTextMatch

Array with details of each full-text match
