Struct RealFileSystem 

pub struct RealFileSystem;

Implementations

impl RealFileSystem

pub fn reclaimable_size<P>(path: P) -> Result<u64>

where P: AsRef<Path>,

The number of bytes actually freed by deleting path.

Symbolic links are never followed. Deleting a link removes only the link, so descending into its target would attribute another tree’s bytes to this candidate and promise space that the clean cannot deliver. Not following them also makes link cycles harmless.

On Unix the figure is allocated blocks rather than apparent length, so sparse files are not overstated, and each inode is counted once so hard links are not double-counted.
