§fn reserve(&mut self, additional: usize, size: usize)
fn reserve(&mut self, additional: usize, size: usize)
Reserves the capacity for at least
additional
more values (of size
total bytes) to
be added to the arguments without a reallocation.§fn add<T>(&mut self, value: T) -> Result<(), Box<dyn Error + Send + Sync>>where
T: Encode<'q, <PgArguments as Arguments<'q>>::Database> + Type<<PgArguments as Arguments<'q>>::Database>,
fn add<T>(&mut self, value: T) -> Result<(), Box<dyn Error + Send + Sync>>where
T: Encode<'q, <PgArguments as Arguments<'q>>::Database> + Type<<PgArguments as Arguments<'q>>::Database>,
Add the value to the end of the arguments.
