Struct SourceCatalogSnapshot 

pub struct SourceCatalogSnapshot {
    pub volume: SourceVolumeSnapshot,
    pub dirs: Vec<SourceDirSnapshot>,
    pub files: Vec<SourceFileSnapshot>,
    pub hardlinks: Vec<SourceHardlinkSnapshot>,
    pub dir_hardlinks: Vec<SourceDirHardlinkSnapshot>,
}

Full capture of a source HFS+/HFSX volume: volume metadata plus every directory and file record. Catalog thread records are not captured — the target writer recreates them from scratch.

Fields

volume: SourceVolumeSnapshot

dirs: Vec<SourceDirSnapshot>

files: Vec<SourceFileSnapshot>

Every captured file row, both user-visible files and the per-inode iNode<N> rows under HFS+ Private Data. Inodes carry is_inode = true and an inode_num; replay must emit them through the dedicated hardlink-inode helper rather than as user-tree files.

hardlinks: Vec<SourceHardlinkSnapshot>

Hardlink stub rows. Each references one is_inode=true entry in files by source CNID.

dir_hardlinks: Vec<SourceDirHardlinkSnapshot>

Directory-hardlink stub rows. Each references one is_dir_inode=true entry in dirs by source CNID.

Implementations

impl SourceCatalogSnapshot

pub fn capture<R: Read + Seek>( fs: &mut HfsPlusFilesystem<R>, ) -> Result<Self, FilesystemError>

Capture volume + every directory + every file record from the source catalog. Walks the leaf-node chain of the catalog B-tree (skipping thread records) and reads each file’s data + resource fork into the snapshot. Index nodes are ignored.

File hardlinks (Step 17) are captured into a separate SourceHardlinkSnapshot list and the inode rows under \0\0\0\0HFS+ Private Data are flagged with is_inode = true. Directory hardlinks (Step 18) still trip the Unsupported guard.

Trait Implementations

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SourceCatalogSnapshot

fn fmt(&self, f: &mut Formatter<'_>) -> Result
