Trait PlaceHolders

pub trait PlaceHolders: Database {
    // Provided methods
    fn placeholders(num: usize, start_num: Option<usize>) -> String { ... }
    fn placeholders_for_bulk_insert_values<I, T>(
        values: I,
        start_num: Option<usize>,
    ) -> String
       where I: Iterator<Item = T>,
             T: Insertable<Database = Self> { ... }
}

Provided Methods

fn placeholders(num: usize, start_num: Option<usize>) -> String

start_num is for only PostgreSQL, it is ignored in other RDB.

fn placeholders_for_bulk_insert_values<I, T>( values: I, start_num: Option<usize>, ) -> String

where I: Iterator<Item = T>, T: Insertable<Database = Self>,

start_num is for only PostgreSQL, it is ignored in other RDB.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
