Struct UpdateBuilder 

pub struct UpdateBuilder { /* private fields */ }

Build an update operation.

This operation is similar to SQL’s UPDATE statement. It allows you to change the values of all or a subset of columns with SQL expressions.

Use the UpdateBuilder to construct an update job. For example:

let result = UpdateBuilder::new(dataset)
    .update_where("region_id = 10")?
    .set("region_name", "New York")?
    .build()?
    .execute()
    .await?;
