TxMetadataMut

netdevice_client::session

Struct TxMetadataMut 

Source 
pub struct TxMetadataMut<'a> { /* private fields */ }
Expand description

A guard for mutating metadata on a Tx buffer.

Holds an exclusive borrow of the underlying descriptor (DescRefMut), ensuring that atomic reference counting is performed only once when obtaining and dropping this guard, rather than on every individual field update.

Implementations§
