Struct AeronMappedFile

pub struct AeronMappedFile { /* private fields */ }

Implementations

impl AeronMappedFile

pub fn new(addr: *mut c_void, length: usize) -> Result<Self, AeronCError>

pub fn new_zeroed() -> Result<Self, AeronCError>

creates zeroed struct where the underlying c struct is on the heap

pub fn addr(&self) -> *mut c_void

pub fn length(&self) -> usize

pub fn aeron_map_new_file( &self, path: &str, fill_with_zeroes: bool, ) -> Result<i32, AeronCError>

pub fn aeron_map_existing_file(&self, path: &str) -> Result<i32, AeronCError>

pub fn aeron_unmap(&self) -> Result<i32, AeronCError>

pub fn get_inner(&self) -> *mut aeron_mapped_file_t

impl AeronMappedFile

pub fn clone_struct(&self) -> Self

Regular clone just increases the reference count of underlying count. clone_struct shallow copies the content of the underlying struct on heap.

NOTE: if the struct has references to other structs these will not be copied

Must be only used on structs which has no init/clean up methods. So its danagerous to use with Aeron/AeronContext/AeronPublication/AeronSubscription More intended for AeronArchiveRecordingDescriptor

Trait Implementations

impl Clone for AeronMappedFile

fn clone(&self) -> AeronMappedFile

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AeronMappedFile

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

Formats the value using the given formatter.

impl Default for AeronMappedFile

This will create an instance where the struct is zeroed, use with care

fn default() -> Self

Returns the “default value” for a type.

impl Deref for AeronMappedFile

type Target = aeron_mapped_file_stct

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
