settings-schema-rs

Derive macro for generating automatically a schema from Rust structures and enums. The schema can be serialized to JSON and/or used to generate a GUI.

Example

Node types

• Section (from struct). Contains fields that can be marked as advanced setting. Unnamed fields are not supported.
• Choice (from enum). Up to one unnamed field per variant is supported. Can be marked with the gui attribute with "drop_down" or "button_group".
• Optional (from Option). Describes data that can be omitted.
• Switch. Can be Enabled (with data) or Disabled. The content can be set to advanced.
• Boolean (from bool).
• Integer (from u/i 8/32/64/size) and Float (from f32/f64). Can be marked with min, max, step, gui attributes. gui can be equal to "text_box", "up_down" or "slider".
• Text (from String).
• Array (from [X; N]).
• Vector (from Vec<X>).
• Dictionary (from Vec<(String, X)>).

Attributes like min, gui can be applied to fields with compound types like Vec<Switch<u64>>.

Custom types with generic type arguments are not supported.

New *Default structures are automatically created to store default values. This is done to allow specifying the default data for all variants in a given enum.
