Struct FileHandle 

pub struct FileHandle<'fs, D: BlockDevice + 'static> { /* private fields */ }

Option-driven mounted file handle.

Writable handles buffer only when they need random-write merge semantics. New files, truncating replacements, and CTZ appends can switch to the streaming CTZ writer, which programs data blocks before the exposing metadata commit. Read-only handles keep only the current offset and ask the mounted snapshot to fill caller buffers on demand.
