Struct MemoryVfs 

pub struct MemoryVfs { /* private fields */ }

A memory-based Virtual File System implementation. Ideal for WASM environments or testing where physical disk access is not available.

Implementations

impl MemoryVfs

pub fn new() -> MemoryVfs

Create a new empty MemoryVfs.

pub fn write_file(&self, uri: &str, content: String)

Upsert a file’s content in the memory VFS.

pub fn remove_file(&self, uri: &str)

Remove a file from the memory VFS.
