Trait FileSetLen

pub trait FileSetLen {
    // Required method
    fn set_len(&self, len: u64) -> Result<()>;
}

A trait for setting the size of a file.

This is equivalent to std::fd::File::set_len method, but wrapped in a trait so that it can be implemented for other types.

Required Methods

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

Set the size of this file.

This is the moral equivalent of ftruncate.

Arguments

• len: the size to set for file.
