Struct RamfsScheme 

pub struct RamfsScheme { /* private fields */ }

Kernel-resident RAM filesystem implementing the Scheme trait.

Implementations

impl RamfsScheme

pub fn new() -> Self

Creates a new instance.

pub fn ensure_dir(&self, path: &str)

Ensure that path (relative to mount root) exists as a directory.

Silently succeeds if the directory already exists.

pub fn insert_file(&self, name: &str, content: &[u8])

Insert a read-only file into the root.

Convenience helper used during vfs::init() to pre-populate files.
