Struct MemoryFs 

pub struct MemoryFs { /* private fields */ }

In-memory filesystem.

Thread-safe via internal RwLock. All data is lost when dropped.

Implementations

impl MemoryFs

pub fn new() -> Self

Create a new empty in-memory filesystem.

Trait Implementations

impl Debug for MemoryFs

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

Formats the value using the given formatter.

impl Default for MemoryFs

fn default() -> Self

Returns the “default value” for a type.
