Struct LengthBounds 

pub struct LengthBounds {
    pub min: usize,
    pub max: usize,
}

Represents the known row count bounds of an operator.

Fields

min: usize

max: usize

Implementations

impl LengthBounds

pub fn maybe_len(&self) -> Option<usize>

pub fn contains(&self, len: usize) -> bool

pub fn intersect_all<I: IntoIterator<Item = LengthBounds>>(iters: I) -> Self

Trait Implementations

impl BitAnd for LengthBounds

type Output = LengthBounds

The resulting type after applying the & operator.

fn bitand(self, rhs: Self) -> Self::Output

Performs the & operation.

impl Clone for LengthBounds

fn clone(&self) -> LengthBounds

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LengthBounds

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<usize> for LengthBounds

fn from(value: usize) -> Self

Converts to this type from the input type.

impl Hash for LengthBounds

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 for LengthBounds

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

Tests for self and other values to be equal, and is used by ==.

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

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