Struct ShmMapping 

pub struct ShmMapping { /* private fields */ }

Owned mapping of a shared-memory segment.

Implementations

impl ShmMapping

pub fn create(name: &str, size: usize) -> Result<ShmMapping, String>

Create a new shared-memory segment, truncate to size, and map it.

pub fn open_existing(name: &str, size: usize) -> Result<ShmMapping, String>

Open an existing shared-memory segment and map it.

pub fn as_ptr(&self) -> *mut u8

Raw pointer to the start of the mapping.

pub fn size(&self) -> usize

Size of the mapping in bytes.

pub fn name(&self) -> &str

Name used to create/open the segment.

pub fn unlink(name: &str) -> Result<(), String>

Unlink the underlying POSIX shared-memory object.

Trait Implementations

impl Drop for ShmMapping

Available on Unix only.

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
