Module: Commutator::Util::Placeholders

Defined in:: lib/commutator/util/placeholders.rb

Overview

Provides a placeholder string for a name or value for use in DynamoDB expressions.

Name placeholders will return the name itself if it is not a reserved word (and therefore safe to use).

Value placeholders are always generated.
