Trait FileApi 

pub trait FileApi {
    type File;

    // Required methods
    fn open(&mut self, filename: &Path) -> Option<Self::File>;
    fn read(file: &mut Self::File, buf: &mut [u8]) -> bool;
    fn seek(file: &mut Self::File, pos: SeekFrom) -> bool;
    fn tell(file: &mut Self::File) -> Option<u64>;
}

The file reading API

Application can provide its own File API to override default. For example, this may be useful in cases when soundfonts isn’t located in the file system.

Open file with specified name

fn read(file: &mut Self::File, buf: &mut [u8]) -> bool

Read binary data from file descriptor

fn seek(file: &mut Self::File, pos: SeekFrom) -> bool

fn tell(file: &mut Self::File) -> Option<u64>

Get current reading position from beginning of file

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.
