Struct ShareModeTable 

pub struct ShareModeTable {
    opens: Mutex<HashMap<String, Vec<OpenMode>>>,
}

Server-wide table of open share modes, keyed by on-disk path, used to detect sharing violations ([MS-FSA] §2.1.5.1) across all connections.

Fields

opens: Mutex<HashMap<String, Vec<OpenMode>>>

Implementations

impl ShareModeTable

pub fn new() -> Self

Create an empty table.

pub fn try_open( &self, path: &str, access: u32, share: u32, owner: LockOwner, ) -> bool

Record a new open if it is compatible with every existing open on the same file; returns false (registering nothing) on a sharing violation.

pub fn close(&self, path: &str, owner: LockOwner)

Drop the open recorded for owner on path.

pub fn close_session(&self, session_id: u64)

Drop every open recorded for any handle of session_id.

pub fn open_count(&self, path: &str) -> usize

Number of opens currently recorded for path.

pub fn has_open_under(&self, dir: &str, exclude: LockOwner) -> bool

True when any open exists on a strict descendant of dir, or on dir itself by an open other than exclude. A directory rename fails while such a subtree handle is held ([MS-FSA] §2.1.5.14.2).

impl Default for ShareModeTable

fn default() -> ShareModeTable
