pub struct RowsFrameBounds {
    pub start: RowsFrameBound,
    pub end: RowsFrameBound,
}

Fields

start: RowsFrameBound

end: RowsFrameBound

Implementations

impl RowsFrameBounds

pub(super) fn from_protobuf(bounds: &PbRowsFrameBounds) -> Result<Self>

pub(super) fn to_protobuf(&self) -> PbRowsFrameBounds

impl RowsFrameBounds

pub fn is_canonical(&self) -> bool

Check if the ROWS frame is canonical.

A canonical ROWS frame is defined as:

• Its bounds are valid (see Self::validate).
• It contains the current row.

pub fn n_preceding_rows(&self) -> Option<usize>

Get the number of preceding rows.

pub fn n_following_rows(&self) -> Option<usize>

Get the number of following rows.

Trait Implementations

impl Clone for RowsFrameBounds

fn clone(&self) -> RowsFrameBounds

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RowsFrameBounds

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

Formats the value using the given formatter.

impl Display for RowsFrameBounds

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

Formats the value using the given formatter.

impl FrameBoundsImpl for RowsFrameBounds

fn validate(&self) -> Result<()>

impl Hash for RowsFrameBounds

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 RowsFrameBounds

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