    pub flags: DescriptorFlags,
}

Packet descriptor / header.

Fields

length: u32

Payload length in Bytes.

channel: u32

The channel this packet belongs to, or -1 for a control packet.

offset: u64

Offset into the memblock, in Bytes.

flags: DescriptorFlags

SHMRELEASE or SHMREVOKE to mark packet as such, or:

For memblock packets:

• Lowest byte: Seek mode

Trait Implementations

impl Clone for Descriptor

fn clone(&self) -> Descriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Descriptor

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

Formats the value using the given formatter.

impl PartialEq for Descriptor

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