Trait ConditionsTarget 

pub trait ConditionsTarget {
    // Required methods
    fn write_where(&mut self);
    fn write_conditions<C: Columns + ?Sized, M>(
        &mut self,
        conditions: Conditions<M>,
        junction: Junction,
    );
}

A query that filter conditions can be written into: a WHERE clause.

Required Methods

fn write_where(&mut self)

Start a WHERE clause, before its conditions.

fn write_conditions<C: Columns + ?Sized, M>( &mut self, conditions: Conditions<M>, junction: Junction, )

Write the conditions of the model M, joined by junction, each comparing the column C stores its domain field in.

Values are bound with their own SQL type; the LIKE operators bind an escaped pattern (… LIKE ? ESCAPE '!'), so user input matches literally.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl ConditionsTarget for DeleteStatement

fn write_where(&mut self)

Nothing: cond_where writes the WHERE itself.

fn write_conditions<C: Columns + ?Sized, M>( &mut self, conditions: Conditions<M>, junction: Junction, )

impl ConditionsTarget for SelectStatement

fn write_where(&mut self)

Nothing: cond_where writes the WHERE itself.

fn write_conditions<C: Columns + ?Sized, M>( &mut self, conditions: Conditions<M>, junction: Junction, )

impl ConditionsTarget for UpdateStatement

fn write_where(&mut self)

Nothing: cond_where writes the WHERE itself.

fn write_conditions<C: Columns + ?Sized, M>( &mut self, conditions: Conditions<M>, junction: Junction, )
