Struct FileSystem 

pub struct FileSystem { /* private fields */ }

A file system change store.

Implementations

impl FileSystem

pub fn filename(&self, hash: &Hash) -> PathBuf

pub fn tag_filename(&self, hash: &Merkle) -> PathBuf

pub fn has_change(&self, hash: &Hash) -> bool

pub fn from_root<P: AsRef<Path>>(root: P, cap: usize) -> Self

Construct a FileSystem, starting from the root of the repository (i.e. the parent of the .pijul directory).

pub fn from_changes(changes_dir: PathBuf, cap: usize) -> Self

Construct a FileSystem, starting from the root of the repository (i.e. the parent of the .pijul directory).

pub fn save_from_buf( &self, buf: &[u8], hash: &Hash, change_id: Option<ChangeId>, ) -> Result<(), ChangeError>

pub fn save_from_buf_unchecked( &self, buf: &[u8], hash: &Hash, change_id: Option<ChangeId>, ) -> Result<(), Error>
