Enum Owner 

pub enum Owner {
    Created,
    Registered,
    Filling,
    Taken,
    Kernel,
    Returned,
    Reusable,
}

Ownership denotes where the ownership stands in long living records and where it is important to know it’s status. All Accept, EpollCtl and Buffer records have varying dynamics how these are allocated and re-used and this requires a flexible type given re-allocation may be expensive in case of buffers whilst desierable just re-create record in Accept or EpollCtl case.

Variants

Created

Record was created (default)

Registered

Registered (e.g. via ProvideBuffers)

Filling

User is filling the created buffer

Taken

Taken is owned intermediately internally before used

Kernel

Record is owned by the Kernel

Returned

Record is returned to the user(space)

Reusable

Record is marked for re-use (e.g. expensive allocation) Typical user: BufferRec

Implementations

impl Owner

pub fn take(&mut self) -> Result<(), TakeError>

Is the Owner in a state that underlying thing can be taken?

Trait Implementations

impl Clone for Owner

fn clone(&self) -> Owner

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Owner

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

Formats the value using the given formatter.

impl Default for Owner

fn default() -> Owner

Returns the “default value” for a type.

impl Display for Owner

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

Formats the value using the given formatter.

impl PartialEq for Owner

fn eq(&self, other: &Owner) -> 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.
