Struct pgx_utils::sql_entity_graph::PostgresType

pub struct PostgresType { /* private fields */ }

A parsed #[derive(PostgresType)] item.

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

Using quote::ToTokens will output the declaration for a PostgresTypeEntity.

use syn::{Macro, parse::Parse, parse_quote, parse};
use quote::{quote, ToTokens};
use pgx_utils::sql_entity_graph::PostgresType;

let parsed: PostgresType = parse_quote! {
    #[derive(PostgresType)]
    struct Example<'a> {
        demo: &'a str,
    }
};
let sql_graph_entity_tokens = parsed.to_token_stream();
