macro_rules! make_row {
{} => { ... };
{$($keys:expr => $vals:expr),+ $(,)?} => { ... };
}Expand description
Outputs a row, given native Rust key => value pairings.
Since instantiating protobuf-generated types is very verbose, this macro exists to make rows with ease:
use pancake_db_client::make_row;
use std::time::SystemTime;
let my_row = make_row! {
"string_col" => "some string".to_string(),
"timestamp_col" => SystemTime::now(),
"int_col" => Some(77),
"bool_col" => Option::<bool>::None,
"bytes_col" => vec![97_u8, 98_u8, 99_u8],
"bool_list_col" => vec![true, false],
};Keys can be any type supporting .to_string().
Values can be any
Rust type that corresponds to a Pancake type, or Options or nested Vecs
thereof.
