Struct datafusion_expr::logical_plan::Limit

pub struct Limit {
    pub skip: usize,
    pub fetch: Option<usize>,
    pub input: Arc<LogicalPlan>,
}

Produces the first n tuples from its input and discards the rest.

Fields

skip: usize

Number of rows to skip before fetch

fetch: Option<usize>

Maximum number of rows to fetch, None means fetching all rows

input: Arc<LogicalPlan>

The logical plan

Trait Implementations

impl Clone for Limit

fn clone(&self) -> Limit

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Hash for Limit

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<Limit> for Limit

fn eq(&self, other: &Limit) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
