[SchemeAsync::on_close] and [SchemeSync::on_close] are only called when the last file descriptor referring to the file description is closed. To implement traditional POSIX advisory file locking, CqeOpcode::RespondAndNotifyOnDetach is used to notify the scheme by sending a [RequestKind::OnDetach] request the next time the file description is “detached” from a file descriptor. Not done by default to avoid unnecessary IPC.

Implementations

impl CqeOpcode

pub fn try_from_raw(raw: u8) -> Option<Self>

Trait Implementations

impl Clone for CqeOpcode

fn clone(&self) -> CqeOpcode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CqeOpcode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for CqeOpcode

fn eq(&self, other: &CqeOpcode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
