Struct Address

pub struct Address {
    pub device_cid: u32,
    pub host_cid: u32,
    pub device_port: u32,
    pub host_port: u32,
}

An address for a vsock packet transmitted over USB. Since this library does not implement policy decisions, it includes all four components of a vsock address pair even though some may not be appropriate for some situations.

Fields

device_cid: u32

For Connect, Reset, Accept, and Data packets this represents the device side’s address. Usually this will be a special value representing either that it is simply “the device”, or zero along with the rest of the cid and port fields to indicate that it’s a control stream packet. Must be zero for any other packet type.

host_cid: u32

For Connect, Reset, Accept, and Data packets this represents the host side’s address. Usually this will be a special value representing either that it is simply “the host”, or zero along with the rest of the cid and port fields to indicate that it’s a control stream packet. Must be zero for any other packet type.

device_port: u32

For Connect, Reset, Accept, and Data packets this represents the device side’s port. This must be a valid positive value for any of those packet types, unless all of the cid and port fields are also zero, in which case it is a control stream packet. Must be zero for any other packet type.

host_port: u32

For Connect, Reset, Accept, and Data packets this represents the host side’s port. This must be a valid positive value for any of those packet types, unless all of the cid and port fields are also zero, in which case it is a control stream packet. Must be zero for any other packet type.

Implementations

impl Address

pub fn is_zeros(&self) -> bool

Returns true if all the fields of this address are zero (which usually means it’s a control packet of some sort).

Trait Implementations

impl Clone for Address

fn clone(&self) -> Address

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Address

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

Formats the value using the given formatter.

impl Default for Address

fn default() -> Address

Returns the “default value” for a type.

impl From<&Header> for Address

fn from(header: &Header) -> Self

Converts to this type from the input type.

impl Hash for Address

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Address

fn cmp(&self, other: &Address) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Address

fn eq(&self, other: &Address) -> 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 PartialOrd for Address

fn partial_cmp(&self, other: &Address) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
