Trait littlefs2::io::Write

pub trait Write {
    fn write(&self, data: &[u8]) -> Result<usize>;
    fn flush(&self) -> Result<()>;

    fn write_all(&self, buf: &[u8]) -> Result<()> { ... }
}

The Write trait allows for writing bytes to a file.

By analogy with std::io::Write, we also define a flush() method. In the current implementation, writes are final and flush has no effect.

Required methods

fn write(&self, data: &[u8]) -> Result<usize>

Write at most data.len() bytes. The file will not necessarily be updated unless flush is called as there is a cache. Upon success, return how many bytes were written.

fn flush(&self) -> Result<()>

Write out all pending writes to storage.
