Implementations

impl DeleteQuery

pub fn new() -> Self

Construct an empty delete query.

pub fn one<E: EntityKind>(self, value: impl FieldValue) -> Self

Delete a single row by primary key value.

Convenience wrapper; entity knowledge lives here only for ergonomics.

pub fn only<E: EntityKind>(self) -> Self

Delete a single row where the primary key is unit.

pub fn many<E, I, V>(self, values: I) -> Self

where E: EntityKind, I: IntoIterator<Item = V>, V: FieldValue,

Delete multiple rows by an arbitrary field.

pub fn one_by_field( self, field: impl AsRef<str>, value: impl FieldValue, ) -> Self

Delete a single row by an arbitrary field value.

pub fn many_by_field<I, V>(self, field: impl AsRef<str>, values: I) -> Self

where I: IntoIterator<Item = V>, V: FieldValue,

Delete multiple rows by an arbitrary field.
