Struct aws_sdk_dynamodb::model::Projection
source · [−]#[non_exhaustive]pub struct Projection {
pub projection_type: Option<ProjectionType>,
pub non_key_attributes: Option<Vec<String>>,
}
Expand description
Represents attributes that are copied (projected) from the table into an index. These are in addition to the primary key attributes and index key attributes, which are automatically projected.
Fields (Non-exhaustive)
This struct is marked as non-exhaustive
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.projection_type: Option<ProjectionType>
The set of attributes that are projected into the index:
-
KEYS_ONLY
- Only the index and primary keys are projected into the index. -
INCLUDE
- In addition to the attributes described inKEYS_ONLY
, the secondary index will include other non-key attributes that you specify. -
ALL
- All of the table attributes are projected into the index.
non_key_attributes: Option<Vec<String>>
Represents the non-key attribute names which will be projected into the index.
For local secondary indexes, the total count of NonKeyAttributes
summed across all of the local secondary indexes, must not exceed 20. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.
