Trait UnifiedFs 

pub trait UnifiedFs {
    type ErrRes: Display;
    type FileOp;

    // Required methods
    async fn metadata(path: &Path) -> Result<Metadata, Self::ErrRes>;
    async fn open<P: AsRef<Path>>(path: P) -> Result<Self::FileOp>;
    async fn read_to_string(
        file: &mut Self::FileOp,
        buf: &mut String,
    ) -> Result<usize>;
}

A trait which unifies the file IO operations.

Required Associated Types

type ErrRes: Display

Error type for metadata operation.

type FileOp

A file realization struct.

Required Methods

async fn metadata(path: &Path) -> Result<Metadata, Self::ErrRes>

Get the metadata for the file specified by the argument path.

async fn open<P: AsRef<Path>>(path: P) -> Result<Self::FileOp>

Open the file specified by the argument path for reading only!

async fn read_to_string( file: &mut Self::FileOp, buf: &mut String, ) -> Result<usize>

Reads from the file of typeSelf::FileOp into a String buffer a file content.

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.
