Trait Progress

pub trait Progress {
    // Required methods
    fn init(
        &mut self,
        size: usize,
        filename: &str,
    ) -> impl Future<Output = ()> + Send;
    fn update(&mut self, size: usize) -> impl Future<Output = ()> + Send;
    fn finish(&mut self) -> impl Future<Output = ()> + Send;
}

This trait is used by users of the lib to implement custom behavior during file downloads

Required Methods

fn init( &mut self, size: usize, filename: &str, ) -> impl Future<Output = ()> + Send

At the start of the download The size is the total size in bytes of the file.

fn update(&mut self, size: usize) -> impl Future<Output = ()> + Send

This function is called whenever size bytes have been downloaded in the temporary file

fn finish(&mut self) -> impl Future<Output = ()> + Send

This is called at the end of the download

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
