Macro mz_sql_parser::ident

macro_rules! ident {
    ($val:expr) => { ... };
    (@internal_check_len $max_len:literal, $val:expr) => { ... };
}

A macro that creates an Ident from a string literal, validating all of our invariants at compile time.

Examples

use mz_sql_parser::ident;

// Checks invariants at compile time, returning an `Ident`.
let id = ident!("my_postgres_source");

assert_eq!(id.as_str(), "my_postgres_source");

use mz_sql_parser::ident;

const TOO_LONG: &str = "I am a very long identifier that is more than 255 characters long which is the max length for idents.\
I am a very long identifier that is more than 255 characters long which is the max length for idents.\
Use that sentance twice since 255 characters is actually a lot.";

// This fails to build since the string is too long.
let _id = ident!(TOO_LONG);
