#[sql_forge_transparent]Expand description
Marks a single-value tuple struct as a transparent wrapper for use with
sql_forge! parameters.
Expands to #[derive(sqlx::Type)] + #[sqlx(transparent)] (needed for
all database backends so the type implements sqlx::Encode + sqlx::Type)
and additionally implements SqlForgeValidatorValue<InnerType>, which is
required for PostgreSQL to pass compile-time parameter validation in
query_as!. MySQL and SQLite do not need to use the trait.
