Struct OrderAnalysis 

pub struct OrderAnalysis {
    pub order_columns: Vec<OrderColumn>,
    pub limit: Option<usize>,
    pub is_windowed: bool,
    pub pattern: OrderPattern,
}

Result of analyzing ORDER BY in a SQL query.

Fields

order_columns: Vec<OrderColumn>

Columns specified in ORDER BY

limit: Option<usize>

LIMIT value if present

is_windowed: bool

Whether the query has a windowed GROUP BY

pattern: OrderPattern

Classified streaming pattern

Implementations

impl OrderAnalysis

pub fn is_streaming_safe(&self) -> bool

Returns true if this ORDER BY pattern is safe for streaming.

Trait Implementations

impl Clone for OrderAnalysis

fn clone(&self) -> OrderAnalysis

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OrderAnalysis

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

Formats the value using the given formatter.

impl PartialEq for OrderAnalysis

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