Implementations§

§

impl<'qb, 'args, DB, Sep> Separated<'qb, 'args, DB, Sep>
where 'args: 'qb, DB: Database, Sep: Display,

pub fn push(&mut self, sql: impl Display) -> &mut Separated<'qb, 'args, DB, Sep>

Push the separator if applicable, and then the given SQL fragment.

See QueryBuilder::push() for details.

pub fn push_unseparated( &mut self, sql: impl Display, ) -> &mut Separated<'qb, 'args, DB, Sep>

Push a SQL fragment without a separator.

Simply calls QueryBuilder::push() directly.

pub fn push_bind<T>(&mut self, value: T) -> &mut Separated<'qb, 'args, DB, Sep>
where T: 'args + Encode<'args, DB> + Type<DB>,

Push the separator if applicable, then append a bind argument.

See QueryBuilder::push_bind() for details.

pub fn push_bind_unseparated<T>( &mut self, value: T, ) -> &mut Separated<'qb, 'args, DB, Sep>
where T: 'args + Encode<'args, DB> + Type<DB>,

Push a bind argument placeholder (? or $N for Postgres) and bind a value to it without a separator.

Simply calls QueryBuilder::push_bind() directly.
