Trait Implementations

impl Clone for ShmInfo

fn clone(&self) -> ShmInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShmInfo

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

Formats the value using the given formatter.

impl PartialEq for ShmInfo

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

impl SentryExchangeable for ShmInfo

SentryExchangeable trait implementation for ShmInfo. Shminfo is a typical structure which is returned by the kernel to the userspace in order to delivers various SHM-related information to a given task that is using the corresponding SHM.

In test mode only, this structure can be written back to the Exchange Area. In production mode, the application can’t write such a content to the exchange as the kernel as strictly no use of it.

fn from_kernel(&mut self) -> Result<Status, Status>

set the current object using the data delivered by the kernel in the exchange zone

fn to_kernel(&self) -> Result<Status, Status>

Copy the current object to the kernel exchagne zone
