Struct smoltcp::phy::DeviceLimits

pub struct DeviceLimits {
    pub max_transmission_unit: usize,
    pub max_burst_size: Option<usize>,
    // some fields omitted
}

A description of device limitations.

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.

Trait Implementations

impl Clone for DeviceLimits

fn clone(&self) -> DeviceLimits

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for DeviceLimits

fn default() -> DeviceLimits

Returns the "default value" for a type.
