structify

structify is designed to parse loosely-typed, client-controlled input such as JSON or a web form submission into a struct. It's purpose is to validate input shape and convert to a struct, not to validate input contents. For example, validating and converting an input field to an integer, not validating that the integer is between 0 and 10.

Example Usage

type Person struct {
  FirstName string
  LastName string
}

var person Person
err := structify.Parse(map[string]any{"FirstName": "John", "LastName": "Smith"}, &person)

Features

• Supports nested structs
• Supports slices
• Automatically maps between camelcase and snakecase. That is, first_name will be mapped to FirstName without needing a struct field tag
• Structured errors that accumulate all field errors
• Automatically uses database/sql.Scanner interface if available
• Can define scanner method on types or register on parser when not convenient to add method to type
• Includes generic Optional type
