Struct LimitExecutor 

pub struct LimitExecutor { /* private fields */ }

Limit executor - applies LIMIT and OFFSET to a relation.

Implementations

impl LimitExecutor

pub fn new(limit: usize, offset: usize) -> Self

Creates a new limit executor.

pub fn limit_only(limit: usize) -> Self

Creates a limit executor with only a limit (no offset).

pub fn execute(&self, input: Relation) -> Relation

Executes the limit on the input relation.

Note: This operation is O(offset + limit) for the actual work, but dropping the unused entries is O(n - offset - limit). In a real query engine, limit would be pushed down to avoid materializing unnecessary rows.
