Class DerivedTypeDuckTyping

Namespace

Nerdbank.MessagePack

Assembly

Nerdbank.MessagePack.dll

A shape-based union that can distinguish between union cases based on their structural characteristics rather than explicit aliases.

Remarks

This union strategy analyzes the provided type shapes to identify distinguishing characteristics such as:

• Required properties that appear only in specific union cases

The resulting converter does not use explicit type aliases and instead inspects the MessagePack structure during deserialization to determine the appropriate union case to deserialize into.

Note that this approach may be slower than alias-based unions as it may require buffering the entire value for analysis.
