Enum WindowFrameBounds

pub enum WindowFrameBounds {
    Bounds {
        start: WindowFrameBound,
        end: Option<WindowFrameBound>,
    },
    Gap(Box<Expr>),

Variants

Bounds

Fields

start: WindowFrameBound

end: Option<WindowFrameBound>

The right bound of the BETWEEN .. AND clause. The end bound of None indicates the shorthand form (e.g. ROWS 1 PRECEDING), which must behave the same as end_bound = WindowFrameBound::CurrentRow.

Gap(Box<Expr>)

Trait Implementations

impl Clone for WindowFrameBounds

fn clone(&self) -> WindowFrameBounds

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WindowFrameBounds

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

Formats the value using the given formatter.

impl Hash for WindowFrameBounds

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 WindowFrameBounds

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