Struct btfproto::local_fs::LocalFs

pub struct LocalFs<A> { /* private fields */ }

A struct for managing the part of a blocktree stored in the local filesystem.

Implementations

impl<A: Authorizer> LocalFs<A>

pub async fn new_empty( btdir: PathBuf, generation: u64, creds: Arc<dyn Creds>, authorizer: A ) -> Result<LocalFs<A>>

Creates a new empty blocktree at the given path.

pub fn new_existing( btdir: PathBuf, creds: Arc<dyn Creds>, authorizer: A ) -> Result<LocalFs<A>>

Opens an existing blocktree stored at the given path.
