Struct ColumnOrder 

pub struct ColumnOrder {
    pub column_index: usize,
    pub order_type: OrderType,
}

Column index with an order type (ASC or DESC). Used to represent a sort key (Vec<ColumnOrder>).

Corresponds to protobuf PbColumnOrder.

Fields

column_index: usize

order_type: OrderType

Implementations

impl ColumnOrder

pub fn new(column_index: usize, order_type: OrderType) -> Self

pub fn shift_with_offset(&mut self, offset: isize)

Shift the column index with offset.

impl ColumnOrder

pub fn from_protobuf(column_order: &PbColumnOrder) -> Self

pub fn to_protobuf(self) -> PbColumnOrder

Trait Implementations

impl Clone for ColumnOrder

fn clone(&self) -> ColumnOrder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnOrder

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

Formats the value using the given formatter.

impl Display for ColumnOrder

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

Formats the value using the given formatter.

impl Hash for ColumnOrder

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 ColumnOrder

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