Struct Field 

pub struct Field {
    pub name: String,
    pub schema: Schema,
    pub required: bool,
    pub doc: String,
}

One field of a Schema::Record. doc is per field because that is what :describe-option and :customize render beside it.

Fields

name: String

The field’s key as a config file spells it. The derive kebab-cases the Rust identifier (max_depth → max-depth) and strips a raw-identifier prefix (r#match → match), so this is the wire name, not the Rust one.

schema: Schema

The shape the field’s value must have.

required: bool

Derived from the Rust type: an Option<T> field is optional, everything else is required. That mapping is the whole reason the derive can decide this without an attribute — the type already says it.

doc: String

The field’s /// doc-comment, lines joined and trimmed; empty when the field has none.
