Trait AsyncNewFile

pub trait AsyncNewFile {
    type Target;
    type Error;

    // Required method
    fn new_async<'async_trait>(    ) -> Pin<Box<dyn Future<Output = Result<Self::Target, Self::Error>> + Send + 'async_trait>>
       where Self: 'async_trait;
}

Trait for types that can be newly constructed asynchronously.

Required Associated Types

type Target

The type created on success.

type Error

The error type.

Required Methods

fn new_async<'async_trait>() -> Pin<Box<dyn Future<Output = Result<Self::Target, Self::Error>> + Send + 'async_trait>>

where Self: 'async_trait,

Creates a new instance of the type Target.

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.

Implementations on Foreign Types

impl AsyncNewFile for TempFile

Available on crate feature async-tempfile only.

type Target = TempFile

type Error = Error

fn new_async<'async_trait>() -> Pin<Box<dyn Future<Output = Result<Self::Target, Self::Error>> + Send + 'async_trait>>

where Self: 'async_trait,
