Struct PostgresHash

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

A parsed #[derive(PostgresHash)] 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::InventoryPostgresHash.

On structs:

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

use pgrx_sql_entity_graph::CodeEnrichment;
let parsed: CodeEnrichment<PostgresHash> = parse_quote! {
    #[derive(PostgresHash)]
    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 pgrx_sql_entity_graph::PostgresHash;

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

Fields

name: Ident

to_sql_config: ToSqlConfig
