Trait LoadFromFile

pub trait LoadFromFile: Sized {

    // Required method
    fn load_from_file<'async_trait>(
        filename: impl 'async_trait + AsRef<Path> + Send,

Required Methods

fn load_from_file<'async_trait>( filename: impl 'async_trait + AsRef<Path> + Send, ) -> Pin<Box<dyn Future<Output = Result<Self, Self::Error>> + Send + 'async_trait>>

where Self: 'async_trait,

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.
