Struct FilesystemStats 

pub struct FilesystemStats { /* private fields */ }

Filesystem capacity and limits for the filesystem containing a target. Values are observations, not reservations. None means unknown or unsupported. Byte counts use the filesystem allocation unit, not its preferred I/O size. Getters preserve zero and false as known values. Fluent with_* setters accept None to restore an unknown value.

use vfsi_core::FilesystemStats;
let stats = FilesystemStats::default()
    .with_free_bytes(Some(0))
    .with_read_only(Some(false));
assert_eq!(stats.free_bytes(), Some(0));
assert_eq!(stats.read_only(), Some(false));
assert_eq!(stats.total_bytes(), None);
