Struct deltalake::arrow::compute::LexicographicalComparator
source · pub struct LexicographicalComparator { /* private fields */ }Expand description
A lexicographical comparator that wraps given array data (columns) and can lexicographically compare data at given two indices. The lifetime is the same at the data wrapped.
Implementations§
source§impl LexicographicalComparator
impl LexicographicalComparator
sourcepub fn compare(&self, a_idx: usize, b_idx: usize) -> Ordering
pub fn compare(&self, a_idx: usize, b_idx: usize) -> Ordering
lexicographically compare values at the wrapped columns with given indices.
sourcepub fn try_new(
columns: &[SortColumn]
) -> Result<LexicographicalComparator, ArrowError>
pub fn try_new( columns: &[SortColumn] ) -> Result<LexicographicalComparator, ArrowError>
Create a new lex comparator that will wrap the given sort columns and give comparison results with two indices.
