Enum JoinCond 

pub enum JoinCond {
    On(String, &'static str, String),
    OnVal(String, &'static str, Value),
    OnRaw(String, Vec<Value>),
}

A single ON condition of a Join.

Columns in On/OnVal are stored raw and escaped at compile time. OnRaw is the verbatim escape hatch (see JoinClause::on_raw).

Variants

On(String, &'static str, String)

lhs op rhs — both sides are columns (escaped at compile time).

OnVal(String, &'static str, Value)

col op ? — col escaped, the value is bound.

OnRaw(String, Vec<Value>)

Verbatim SQL with its own binds.

Trait Implementations

impl Clone for JoinCond

fn clone(&self) -> JoinCond

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JoinCond

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

Formats the value using the given formatter.

impl PartialEq for JoinCond

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