Struct Dir 

pub struct Dir(/* private fields */);

A clone-able (internally Arc-ed), thread-safe in-memory filesystem.

This was built for MemoryAssetReader and is primarily used by unit tests and by the embedded backend.

impl Dir

pub fn new(path: PathBuf) -> Dir

Creates a new Dir for the given path.

pub fn insert_asset_text(&self, path: &Path, asset: &str)

Inserts textual data as an asset, at the path relative to this Dir.

pub fn insert_meta_text(&self, path: &Path, asset: &str)

Inserts textual data as asset metadata, at the path relative to this Dir.

pub fn insert_asset(&self, path: &Path, value: impl Into<Value>)

Inserts a Vec of bytes or a 'static array of bytes as an asset, at the path relative to this Dir.

pub fn remove_asset(&self, path: &Path) -> Option<Data>

Removes the stored asset at path.

Returns the Data stored if found, None otherwise.

pub fn insert_meta(&self, path: &Path, value: impl Into<Value>)

Inserts a Vec of bytes or a 'static array of bytes as asset metadata, at the path relative to this Dir.

pub fn remove_metadata(&self, path: &Path) -> Option<Data>

Removes the stored metadata at path.

Returns the Data stored if found, None otherwise.

pub fn get_or_insert_dir(&self, path: &Path) -> Dir
