Struct smoltcp::phy::DeviceCapabilities

pub struct DeviceCapabilities {
    pub max_transmission_unit: usize,
    pub max_burst_size: Option<usize>,
    pub checksum: ChecksumCapabilities,
    /* private fields */
}

A description of device capabilities.

Higher-level protocols may achieve higher throughput or lower latency if they consider the bandwidth or packet size limitations.

Fields

max_transmission_unit: usize

Maximum transmission unit.

The network device is unable to send or receive frames larger than the value returned by this function.

For Ethernet, MTU will fall between 576 (for IPv4) or 1280 (for IPv6) and 9216 octets.

max_burst_size: Option<usize>

Maximum burst size, in terms of MTU.

The network device is unable to send or receive bursts large than the value returned by this function.

If None, there is no fixed limit on burst size, e.g. if network buffers are dynamically allocated.

checksum: ChecksumCapabilities

The set of protocols for which checksum can be computed in hardware.

Trait Implementations

impl Clone for DeviceCapabilities

fn clone(&self) -> DeviceCapabilities

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DeviceCapabilities

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

Formats the value using the given formatter.

impl Default for DeviceCapabilities

fn default() -> DeviceCapabilities

Returns the “default value” for a type.
