Struct pgrx_sql_entity_graph::PostgresEnum

pub struct PostgresEnum { /* private fields */ }

A parsed #[derive(PostgresEnum)] item.

It should be used with syn::parse::Parse functions.

Using quote::ToTokens will output the declaration for a pgrx::datum::pgrx_sql_entity_graph::PostgresEnumEntity.

use syn::{Macro, parse::Parse, parse_quote, parse};
use quote::{quote, ToTokens};
use pgrx_sql_entity_graph::PostgresEnum;

use pgrx_sql_entity_graph::CodeEnrichment;
let parsed: CodeEnrichment<PostgresEnum> = parse_quote! {
    #[derive(PostgresEnum)]
    enum Demo {
        Example,
    }
};
let sql_graph_entity_tokens = parsed.to_token_stream();
