Derive Macro IntoDoc 

#[derive(IntoDoc)]
{
    // Attributes available to this derive:
    #[zvec]
}

Derive an IntoDoc impl that constructs a zvec::Doc from &self.

Field attributes

Each field accepts at most one #[zvec(...)] attribute. Recognised keys:

key	effect
pk	Use this field as the document’s primary key (must be a String).
rename = "other"	Use "other" as the field name in zvec instead of the Rust ident.
skip	Don’t emit this field at all.
binary	Treat Vec<u8> as DataType::Binary.
vector_fp32	Treat Vec<f32> as DataType::VectorFp32.
vector_fp64	Treat Vec<f64> as DataType::VectorFp64.
vector_int8	Treat Vec<i8> as DataType::VectorInt8.
vector_int16	Treat Vec<i16> as DataType::VectorInt16.

Supported field types (without explicit type hint)

String, bool, i32, i64, u32, u64, f32, f64. Each of these may be wrapped in Option<T> — None emits Doc::set_field_null(name).

Vec<_>-typed fields require an explicit type hint (see table above), because the same Rust type can map to several different zvec DataTypes.
