Expand description

Implementing this trait allows one to hook into requests to the Serum DEX via a frontend proxy.

Provided methods

Called before any instruction, giving middleware access to the raw instruction data. This can be used to access extra data that is prepended to the DEX data, allowing one to expand the capabilities of any instruction by reading the instruction data here and then using it in any of the method handlers.

Called when the instruction data doesn’t match any DEX instruction.
