substrate-data-derive

#[derive(Schema)] for substrate-data.

Layer and context: shared kernel · data

• For: generating Schema for structs and enums: reading with paths, writing, binary and frame forms, the shape description, and #[data(...)] options (rename, default, skip, range, tag, view).
• Not for: the model, the forms and the schema traits themselves; they live in substrate-data, which re-exports the derive. Depend on that crate, not on this one.

Usage

use substrate_data::Schema;

#[derive(Schema, Debug, PartialEq)]
struct Project {
    /// The project's name.
    name: String,
    #[data(default)]
    archived: bool,
}

let project: Project = substrate_data::from_text(r#"{ name: "site" }"#).unwrap().value;
assert_eq!(project, Project { name: "site".into(), archived: false });

The full list of attributes is in the crate documentation and docs/format.md.
