Struct PostgresOrd

pub struct PostgresOrd {
    pub name: Ident,
    pub to_sql_config: ToSqlConfig,
}

A parsed #[derive(PostgresOrd)] item.

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

Using quote::ToTokens will output the declaration for a pgx::datum::sql_entity_graph::InventoryPostgresOrd.

On structs:

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

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

On enums:

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

let parsed: PostgresOrd = parse_quote! {
    #[derive(PostgresOrd)]
    enum Demo {
        Example,
    }
};
let sql_graph_entity_tokens = parsed.to_token_stream();

Fields

name: Ident

to_sql_config: ToSqlConfig
