Struct InMemoryFs 

pub struct InMemoryFs { /* private fields */ }

A fully in-memory filesystem implementation.

Thread-safe via Arc<RwLock<...>> — all VirtualFs methods take &self. Cloning is cheap (Arc increment) which is useful for subshell state cloning.

Implementations

impl InMemoryFs

pub fn new() -> Self

pub fn deep_clone(&self) -> Self

Create a completely independent copy of this filesystem.

Unlike Clone (which shares data via Arc), this recursively clones the entire FsNode tree so the copy and original are fully independent. Used for subshell isolation: ( cmds ).

Trait Implementations

impl Clone for InMemoryFs

fn clone(&self) -> InMemoryFs

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InMemoryFs

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

Formats the value using the given formatter.

impl Default for InMemoryFs

fn default() -> Self

Returns the “default value” for a type.
