Struct InMemoryStorage 

pub struct InMemoryStorage { /* private fields */ }

In-memory VFS storage implementation.

Stores files and directories in memory using HashMap and HashSet. Thread-safe via a single RwLock over the combined state.

Implementations

impl InMemoryStorage

pub fn new() -> Self

Create a new empty in-memory storage with root directory.

Trait Implementations

impl Debug for InMemoryStorage

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

Formats the value using the given formatter.

impl Default for InMemoryStorage

fn default() -> Self

Returns the “default value” for a type.
