Struct ProjectedFs 

pub struct ProjectedFs { /* private fields */ }

A projected filesystem that resolves paths against the DAG and serves file content from the CAS. An overlay captures writes.

Implementations

impl ProjectedFs

pub fn new(dag: Dag, root: ContentHash) -> Self

pub fn read_file(&self, path: &str) -> Result<Vec<u8>, ProjectedError>

Read a file’s contents. Checks the overlay first, then the DAG/CAS.

pub fn list_dir(&self, path: &str) -> Result<Vec<String>, ProjectedError>

List entries in a directory.

pub fn exists(&self, path: &str) -> bool

Check if a path exists (file or directory).

pub fn overlay_mut(&mut self) -> &mut Overlay

Get a mutable reference to the overlay.

pub fn overlay(&self) -> &Overlay

Get a reference to the overlay.

pub fn root(&self) -> &ContentHash

Get the current root hash.

pub fn set_root(&mut self, root: ContentHash)

Update the root hash (after DAG invalidation).

pub fn dag(&self) -> &Dag

Get a reference to the DAG.
