Struct OrdinalRef 

pub struct OrdinalRef {
    pub row_id: RowInstanceId,
    pub ordinal: usize,
}

One stable structural ordinal within a specific row instance.

Fields

row_id: RowInstanceId

Row instance owning the ordinal.

ordinal: usize

Zero-based ordinal within that row instance.

Implementations

impl OrdinalRef

pub fn new(row_id: RowInstanceId, ordinal: usize) -> Self

Creates one stable row/ordinal reference.

Trait Implementations

impl PartialEq for OrdinalRef

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for OrdinalRef

fn partial_cmp(&self, other: &OrdinalRef) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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