Struct FileWriter 

Source 
pub struct FileWriter<'fs, D: BlockDevice + 'static> { /* private fields */ }
Expand description

Create-only file writer for the mounted mutable API.

Small files stay buffered so callers can seek before close. Once sequential writes cross the inline threshold, the handle streams CTZ data blocks before publishing the close-time metadata commit.
