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). Fields can be marked with custom strings or flags. 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). None is used when the content is "default" or calculated.
• Switch. Can be Enabled (with data) or Disabled.
• Boolean (from bool).
• Number (from u/i 8/32/64/size and f32/f64). Attribute gui can be textbox or slider (with sub attribtes min, max, step and logarithmic).
• Text (from String).
• Array (from [X; N]).
• Vector (from Vec<X>).
• Dictionary (from Vec<(String, X)>).

Attributes like 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.
