Struct VipsInstance 

pub struct VipsInstance {}

A singleton instance to manage libvips initialization and shutdown.

Example

use vips::*;

fn main() -> Result<()> {
    let _instance = VipsInstance::new("app_test", true)?;
    // Your libvips code here
    Ok(())
}

Implementations

impl VipsInstance

pub fn new(name: &str, leak_test: bool) -> Result<VipsInstance>

Create a new VipsInstance, initializing libvips. This can only be done once per program execution. Subsequent attempts will return an error.

Arguments

• name - Application name for libvips initialization.
• leak_test - If true, enables leak testing in libvips.

Errors

Returns an error if an instance already exists.

Example

use vips::*;

fn main() -> Result<()> {
    let _instance = VipsInstance::new("app_test", true)?;
    // Your libvips code here
    Ok(())
}

Safety Note

Shutdown Timing: The libvips library is automatically shut down when the VipsInstance is dropped (typically at the end of main()). Any operations referencing libvips after this point (such as in other static destructors or background threads) may result in undefined behavior. To avoid this, ensure all libvips operations are completed before the Vips Instance is dropped.
