dynamodb-expression
A Rust crate to help build DynamoDB condition, filter, key condition, and update expressions in a type-safe way, including using expression attribute names and expression attribute values.
An example showing a how to use this crate to perform a query:
use aws_config::BehaviorVersion;
use aws_sdk_dynamodb::Client;
use dynamodb_expression::{Expression, Num, Path};
let client = Client::new(&aws_config::load_defaults(BehaviorVersion::latest()).await);
let query_output = Expression::builder()
.with_filter(
"name"
.parse::<Path>()?
.attribute_exists()
.and("age".parse::<Path>()?.greater_than_or_equal(Num::new(2.5))),
)
.with_projection(["name", "age"])
.with_key_condition("id".parse::<Path>()?.key().equal(Num::new(42)))
.build()
.query(&client)
.table_name("people")
.send()
.await?;
