pub struct Separated<'qb, 'args: 'qb, DB, Sep>
where DB: Database,
{ /* private fields */ }
Expand description

A wrapper around QueryBuilder for creating comma(or other token)-separated lists.

See QueryBuilder::separated() for details.

Implementations§

source§

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

source

pub fn push(&mut self, sql: impl Display) -> &mut Self

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

See QueryBuilder::push() for details.

source

pub fn push_unseparated(&mut self, sql: impl Display) -> &mut Self

Push a SQL fragment without a separator.

Simply calls QueryBuilder::push() directly.

source

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

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

See QueryBuilder::push_bind() for details.

source

pub fn push_bind_unseparated<T>(&mut self, value: T) -> &mut Self
where T: 'args + Encode<'args, DB> + Send + 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.
