Struct EthernetTx

pub struct EthernetTx { /* private fields */ }

Implementations

impl EthernetTx

pub fn new(sender: Box<dyn EthernetTxEventSender>) -> Self

Return a pinned EthernetTx.

Pinning the returned value is imperative to ensure future to_c_binding() calls will return pointers that are valid for the lifetime of the returned value.

pub unsafe fn to_ffi(&self) -> FfiEthernetTx

Returns a FfiEthernetTx containing functions to queue EthernetTxEvent values into the corresponding EthernetTx.

Note that the pointers in the returned FfiEthernetTx are all to static and pinned values so it’s safe to move this EthernetTx after calling this function.

Safety

This method unsafe because we cannot guarantee the returned FfiEthernetTxCtx will have a lifetime that is shorther than this EthernetTx.

By using this method, the caller promises the lifetime of this EthernetTx will exceed the ctx pointer used across the FFI boundary.
