Struct AttachSpec 

pub struct AttachSpec {
    pub alias: String,
    pub kind: String,
    pub path: Option<String>,
    pub writable: Option<bool>,
    pub on_missing: Option<String>,
}

One database to attach for the duration of a single copy_query call. Same kind-tagged shape as AttachDatabaseParams so the vocabulary stays consistent once remote kinds (tcp / grpc) arrive.

Fields

alias: String

Alias used to qualify tables from this attachment (e.g. src lets you reference src.public.customers). Must be a SQL identifier and cannot be local.

kind: String

Attachment kind. Only "local_file" is supported today; "tcp" (standard remote hyperd) and "grpc" (Data 360 read-only Hyper) are planned.

path: Option<String>

Absolute path to a .hyper file. Required when kind == "local_file"; ignored otherwise.

writable: Option<bool>

If true, allow writes into this attachment. Defaults to false. Must also satisfy the server’s --read-only flag (it always wins).

on_missing: Option<String>

What to do when kind == "local_file" and path does not yet exist. "error" (default) returns FILE_NOT_FOUND; "create" issues CREATE DATABASE IF NOT EXISTS first and then attaches the resulting empty file. "create" requires writable: true and is rejected when the server is --read-only.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema
