Struct DeleteAction

pub struct DeleteAction { /* private fields */ }

Implementations

impl DeleteAction

pub fn new<P, S>(path: P, subset: S) -> Self

where P: Into<Path>, S: Into<Set>,

Creates a DeleteAction for the specified Path and items in that set.

Prefer Path::delete over this.

pub fn and<T>(self, other: T) -> Update

where T: Into<Update>,

Add an additional Update statement to this ADD statement.

use dynamodb_expression::{update::DeleteAction, value::NumSet, Num, Path};

let update = DeleteAction::new("foo".parse::<Path>()?, NumSet::from([7]))
    .and("bar".parse::<Path>()?.set("a value"))
    .and("baz".parse::<Path>()?.remove());
assert_eq!(r#"SET bar = "a value" REMOVE baz DELETE foo [7]"#, update.to_string());

Trait Implementations

impl Clone for DeleteAction

impl From<DeleteAction> for Delete

fn from(action: DeleteAction) -> Self

Converts to this type from the input type.

impl From<DeleteAction> for Update

fn from(value: DeleteAction) -> Self

impl PartialEq for DeleteAction

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