Trait WriteImageToAsync 

pub trait WriteImageToAsync<'a>: WriteSupportingVfsAsync {
    type WriteImageFuture: Future<Output = VfsResult<(), Self>> + Send + Unpin + 'a;

    // Required method
    fn write_image_async(
        self: Pin<&'a Self>,
        path: <Self::Path as PathType>::OwnedPath,
        image: DynamicImage,
        format: ImageFormat,
    ) -> Self::WriteImageFuture;
}

Available on crate features async and image only.

A trait implemented by async vfs implementations that support writing images.

Required Associated Types

type WriteImageFuture: Future<Output = VfsResult<(), Self>> + Send + Unpin + 'a

The future type returned by the write_image_async method.

Required Methods

fn write_image_async( self: Pin<&'a Self>, path: <Self::Path as PathType>::OwnedPath, image: DynamicImage, format: ImageFormat, ) -> Self::WriteImageFuture

Writes an image file at the specified path, using the specified image and format.

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.

Implementors

impl<'vfs> WriteImageToAsync<'vfs> for TokioFsVfs

Available on crate feature tokio only.

type WriteImageFuture = Pin<Box<dyn Future<Output = Result<(), Error<PathBuf>>> + Send + 'vfs>>
