Function init 

pub fn init(app_name: Option<&str>) -> Result<()>

Initialize libvips (idempotent). app_name can be used for logging and diagnostic display. If app_name is None, a default name “vips-rs” will be used.

Errors

Returns Error::InitFailed if initialization fails.

Example

use vips::*;

fn main() -> Result<()> {
    init(Some("my_app"))?;
    // Your libvips code here
    Ok(())
}
