binding

internal/delivery/http/binding

Pattern used

• NormalizeBinder wraps any echo.Binder: delegates bind, then trims and optionally case-converts string fields via struct tags (trim:"false", case:"lower", case:"upper").
• Handles nested structs, pointers, and slices.
• Injected into NewServer via constructor; pass nil for the default normalize binder.

How to extend

• New normalization: add a struct tag, read it in normalizeStruct, apply in a helper. Add tests.
• Custom binder: implement echo.Binder, pass it to NewServer in wiring.
• Opt-out per field: trim:"false".
