Module starts_with 

Functions

starts_with_empty_prefix

starts_with with an empty prefix — DynamoDB rejects empty string key values.

starts_with_empty_prefix_sql

starts_with with an empty prefix on SQL — lowers to LIKE ‘%’, matches all rows.

starts_with_no_match

starts_with with a prefix that matches nothing — returns empty result.

starts_with_non_key_attr

starts_with on a non-key attribute. On DynamoDB this uses FilterExpression; on SQL it lowers to LIKE.

starts_with_optional_field

starts_with on an Option<String> field — matches non-null values with the given prefix; rows with NULL values are excluded.

starts_with_partition_key_error

starts_with on the partition key — on scan-capable drivers (DynamoDB) this falls back to a table scan with a begins_with filter and succeeds; on non-scan NoSQL drivers it returns an error.

starts_with_sort_key

starts_with on the sort key. On DynamoDB this uses KeyConditionExpression; on SQL it lowers to LIKE.

starts_with_special_chars

starts_with prefix containing SQL LIKE wildcards (%, _) and the chosen escape char (!). On SQL drivers the prefix is escaped before being lowered to LIKE so these characters match literally.
