Trait StorageFile 

pub trait StorageFile:
    Read
    + Write
    + Seek
    + Sealed {
    // Required method
    fn set_len(&mut self, new_len: u64) -> Result<()>;
}

This trait is the combination of the std::io stream traits with an additional method to resize the file.

Required Methods

fn set_len(&mut self, new_len: u64) -> Result<()>

Performs the resize. Assumes the same behaviour as std::fs::File::set_len.
