Module pstoedit::driver_info

Information on pstoedit drivers.

Inquire information on drivers using DriverInfo::get or DriverInfo::get_native, and iterate over it to yield a DriverDescription for each driver.

Examples

use std::collections::HashSet;
use pstoedit::DriverInfo;

pstoedit::init()?;

let drivers = DriverInfo::get()?;
let native_drivers = DriverInfo::get_native()?;

// The number of non-native drivers cannot be negative
let num = drivers.iter().count();
let num_native = native_drivers.iter().count();
assert!(num >= num_native);

// Ensure all drivers have a unique symbolic name
let mut formats = HashSet::new();
for driver in &drivers {
    assert!(formats.insert(driver.symbolic_name()?));
}

// Ensure all native drivers are included in the list of all drivers
for driver in &native_drivers {
    assert!(formats.contains(driver.symbolic_name()?));
}
