Trait FileProvider

pub trait FileProvider {
    // Required method
    fn read_bytes<P: AsRef<Path>>(
        &self,
        path: P,
    ) -> Result<Cow<'_, [u8]>, Error>;

    // Provided method
    fn read_str<P: AsRef<Path>>(&self, path: P) -> Result<Cow<'_, str>, Error> { ... }
}

A trait for providing file contents.

Required Methods

fn read_bytes<P: AsRef<Path>>(&self, path: P) -> Result<Cow<'_, [u8]>, Error>

Reads the contents of the file at the given path as bytes.

Errors

• If an error occurs while reading the file.
• If the file does not exist.

Provided Methods

fn read_str<P: AsRef<Path>>(&self, path: P) -> Result<Cow<'_, str>, Error>

Reads the contents of the file at the given path.

Errors

• If an error occurs while reading the file.
• If the file does not exist.
• If the file is not valid UTF-8.

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.
