Struct mz_persist_types::arrow::ArrayBound

pub struct ArrayBound {
    raw: ArrayRef,
    ord: ArrayOrd,
    index: usize,
}

An array with precisely one entry, for use as a lower bound.

Fields

raw: ArrayRef

ord: ArrayOrd

index: usize

Implementations

impl ArrayBound

pub fn new(array: ArrayRef, index: usize) -> Self

Create a new ArrayBound for this array, with the bound at the provided index.

pub fn get(&self) -> ArrayIdx<'_>

Get the value of the bound.

pub fn to_proto_lower(&self, max_len: usize) -> Option<ProtoArrayData>

Convert to an array-data proto, respecting a maximum data size. The resulting proto will decode to a single-row array, such that ArrayBound::new(decoded, 0).get() <= self.get(), which makes it suitable as a lower bound.

Trait Implementations

impl Clone for ArrayBound

fn clone(&self) -> ArrayBound

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ArrayBound

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

Formats the value using the given formatter.

impl PartialEq for ArrayBound

fn eq(&self, other: &Self) -> 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.
