[−][src]Struct ipmpsc::SharedRingBuffer
Represents a file-backed shared memory ring buffer, suitable for
constructing a Receiver
or
Sender
.
Note that it is possible to create multiple
SharedRingBuffer
s for a
given path in a single process, but it is much more efficient
to clone an exisiting instance than construct one from
scratch using one of the constructors.
Methods
impl SharedRingBuffer
[src]
pub fn create(path: &str, size_in_bytes: u32) -> Result<SharedRingBuffer, Error>
[src]
Creates a new
SharedRingBuffer
backed by a
file with the specified name.
The file will be created if it does not already exist or truncated otherwise.
Once this function completes successfully, the same path may
be used to create one or more corresponding instances in other
processes using the
SharedRingBuffer::open
method.
pub fn create_temp(
size_in_bytes: u32
) -> Result<(String, SharedRingBuffer), Error>
[src]
size_in_bytes: u32
) -> Result<(String, SharedRingBuffer), Error>
Creates a new SharedRingBuffer
backed by a
temporary file which will be deleted when the
SharedRingBuffer
is dropped.
The name of the file is returned along with the
SharedRingBuffer
and may be used to create
one or more corresponding instances in other processes using the
SharedRingBuffer::open
method.
pub fn open(path: &str) -> Result<SharedRingBuffer, Error>
[src]
Creates a new SharedRingBuffer
backed by a file with
the specified name.
The file must already exist and have been initialized by a
call to
SharedRingBuffer::create
or
SharedRingBuffer::create_temp
.
