Struct gdal::DriverManager

pub struct DriverManager;

A wrapper around GDALDriverManager. This struct helps listing and registering Drivers.

Implementations

impl DriverManager

pub fn count() -> usize

Returns the number of registered drivers.

Example

use gdal::DriverManager;
println!("{} drivers are registered", DriverManager::count());

203 drivers are registered

pub fn get_driver(index: usize) -> Result<Driver>

Returns the driver with the given index, which must be less than the value returned by DriverManager::count().

See also: count

Example

use gdal::DriverManager;
assert!(DriverManager::count() > 0);
let d = DriverManager::get_driver(0)?;
println!("'{}' is '{}'", d.short_name(), d.long_name());

'VRT' is 'Virtual Raster'

pub fn get_driver_by_name(name: &str) -> Result<Driver>

Returns the driver with the given short name or Err if not found.

See also: count, get

Example

use gdal::DriverManager;
let cog_driver = DriverManager::get_driver_by_name("COG")?;
println!("{}", cog_driver.long_name());

Cloud optimized GeoTIFF generator

pub fn register_driver(driver: &Driver) -> usize

Register a driver for use.

Wraps GDALRegisterDriver()

pub fn deregister_driver(driver: &Driver)

Deregister the passed driver.

Wraps GDALDeregisterDriver()

pub fn register_all()

Register all known GDAL drivers.

Wraps GDALAllRegister()

pub fn prevent_auto_registration()

Prevents the automatic registration of all known GDAL drivers when first calling create, open, etc.

pub fn destroy()

Destroys the driver manager, i.e., unloads all drivers.
