Struct LayoutSignature 

pub struct LayoutSignature {
    pub relation_id: u32,
    pub key_columns: Vec<usize>,
    pub row_count: u32,
}

Stable identity for a sorted relation layout.

Fields

relation_id: u32

Runtime relation identifier.

key_columns: Vec<usize>

Columns used as the sorted key prefix.

row_count: u32

Logical rows in the sorted layout.

Trait Implementations

impl Clone for LayoutSignature

fn clone(&self) -> LayoutSignature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LayoutSignature

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

Formats the value using the given formatter.

impl PartialEq for LayoutSignature

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