CompiledJoinKey

oxirs_arq::jit::join_compiler

Struct CompiledJoinKey 

Source 
pub struct CompiledJoinKey { /* private fields */ }
Expand description

A compiled join-key comparator produced by JoinCompiler::compile.

The wrapped function returns 1 if all key columns match and 0 otherwise.

§Ownership / safety invariant

fn_ptr is only valid while _module_owner is alive. Cloning an Arc<CompiledJoinKey> extends the lifetime safely.

Implementations§

Source§

impl CompiledJoinKey

Source

pub fn compare(&self, left: &[f64], right: &[f64]) -> bool

Compare two rows using the compiled function.

Returns true if all key columns match according to each column’s comparison mode.

§Safety

left must have at least max(spec.left_idx) + 1 elements and right must have at least max(spec.right_idx) + 1 elements.

Source

pub fn key_count(&self) -> usize

The number of key columns this comparator was compiled for.
