Required Methods§

Source

fn stat<'life0, 'async_trait>( &'life0 self, id: FileId, ) -> Pin<Box<dyn Future<Output = NfsResult<NodeInfo>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Return minimal information about an object.

Source

fn lookup<'life0, 'life1, 'async_trait>( &'life0 self, dir_id: FileId, name: &'life1 str, ) -> Pin<Box<dyn Future<Output = NfsResult<FileId>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Look up a child entry by name in a directory.

Source

fn lookup_parent<'life0, 'async_trait>( &'life0 self, id: FileId, ) -> Pin<Box<dyn Future<Output = NfsResult<FileId>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

where Self: 'async_trait, 'life0: 'async_trait,

List a directory’s entries.

Do not synthesize "." or ".."; the server handles cookie and reply formatting for the entries returned here.

Source

fn read<'life0, 'async_trait>( &'life0 self, id: FileId, offset: u64, count: u32, ) -> Pin<Box<dyn Future<Output = NfsResult<(Vec<u8>, bool)>> + Send + 'async_trait>>

Read file data.

Source

fn write<'life0, 'life1, 'async_trait>( &'life0 self, id: FileId, offset: u64, data: &'life1 [u8], ) -> Pin<Box<dyn Future<Output = NfsResult<u32>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Write file data. Returns bytes written.

Source

fn truncate<'life0, 'async_trait>( &'life0 self, id: FileId, size: u64, ) -> Pin<Box<dyn Future<Output = NfsResult<()>> + Send + 'async_trait>>

Source

fn create_dir<'life0, 'life1, 'async_trait>( &'life0 self, dir_id: FileId, name: &'life1 str, ) -> Pin<Box<dyn Future<Output = NfsResult<FileId>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Source

fn remove<'life0, 'life1, 'async_trait>( &'life0 self, dir_id: FileId, name: &'life1 str, ) -> Pin<Box<dyn Future<Output = NfsResult<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Source

fn rename<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, from_dir: FileId, from_name: &'life1 str, to_dir: FileId, to_name: &'life2 str, ) -> Pin<Box<dyn Future<Output = NfsResult<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Rename or move an entry.
