Enum CollationSource 

pub enum CollationSource {
    Explicit,
    Schema,
    Default,
}

Source of a collation for precedence resolution (§13.6).

When two operands in a comparison have different collation sources, the higher-precedence source wins.

Variants

Explicit

Explicit COLLATE clause in the expression (highest precedence).

Schema

Column schema collation (CREATE TABLE ... COLLATE NOCASE).

Default

Default (BINARY) when no other source applies (lowest precedence).

Trait Implementations

impl Clone for CollationSource

fn clone(&self) -> CollationSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CollationSource

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

Formats the value using the given formatter.

impl PartialEq for CollationSource

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