Struct dynamodb_expression::update::SetRemove

pub struct SetRemove { /* private fields */ }

Represents a Set or Remove statement for a DynamoDB expression. Most of the time you won’t use this directly.

See: Set::and, Remove::and

use dynamodb_expression::{Num, Path};

let set = "foo".parse::<Path>()?.set(Num::new(7)).and("bar".parse::<Path>()?.set("a value"));
assert_eq!(r#"SET foo = 7, bar = "a value""#, set.to_string());

let remove = "baz".parse::<Path>()?.remove().and("quux".parse::<Path>()?.remove());
assert_eq!("REMOVE baz, quux", remove.to_string());

let set_remove = set.and(remove);
assert_eq!(r#"SET foo = 7, bar = "a value" REMOVE baz, quux"#, set_remove.to_string());

Implementations

impl SetRemove

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

where T: Into<SetRemove>,

Add an additional Set or Remove statement to this expression.

use dynamodb_expression::{Num, Path, update::SetRemove};

let set = "foo"
    .parse::<Path>()?
    .set(Num::new(7))
    .and("bar".parse::<Path>()?.set("a value"))
    .and("baz".parse::<Path>()?.remove());
assert_eq!(r#"SET foo = 7, bar = "a value" REMOVE baz"#, set.to_string());

Trait Implementations

impl Clone for SetRemove

fn clone(&self) -> SetRemove

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SetRemove

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

Formats the value using the given formatter.

impl Display for SetRemove

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

Formats the value using the given formatter.

impl From<Assign> for SetRemove

fn from(value: Assign) -> Self

Converts to this type from the input type.

impl From<IfNotExists> for SetRemove

fn from(value: IfNotExists) -> Self

Converts to this type from the input type.

impl From<ListAppend> for SetRemove

fn from(value: ListAppend) -> Self

Converts to this type from the input type.

impl From<Math> for SetRemove

fn from(value: Math) -> Self

Converts to this type from the input type.

impl From<Remove> for SetRemove

impl PartialEq for SetRemove

fn eq(&self, other: &SetRemove) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
