Struct Delete 

pub struct Delete {
    pub from: Source,
    pub filter: Filter,
    pub returning: Option<Returning>,
}

A DELETE statement that removes existing records.

Specifies a source to delete from, a filter selecting which records to delete, and an optional returning clause.

Examples

use toasty_core::stmt::{Delete, Source, Filter};
use toasty_core::schema::app::ModelId;

let delete = Delete {
    from: Source::from(ModelId(0)),
    filter: Filter::default(),
    returning: None,
};

Fields

from: Source

The source to delete from (FROM clause).

filter: Filter

Filter selecting which records to delete (WHERE clause).

returning: Option<Returning>

Optional RETURNING clause.

Implementations

impl Delete

pub fn selection(&self) -> Query

Returns a Query that selects the records this delete would remove.

Trait Implementations

impl Clone for Delete

fn clone(&self) -> Delete

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Delete

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

Formats the value using the given formatter.

impl<'a, T> IntoExprTarget<'a, T> for &'a Delete

where T: Resolve,

fn into_expr_target(self, schema: &'a T) -> ExprTarget<'a>

Converts self into an ExprTarget using the provided schema.

impl Node for Delete

fn visit<V>(&self, visit: V)

where V: Visit,

Traverses this node with an immutable visitor.

fn visit_mut<V>(&mut self, visit: V)

where V: VisitMut,

Traverses this node with a mutable visitor.

impl PartialEq for Delete

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