Trait x86_64::structures::port::PortRead
source · pub trait PortRead {
// Required method
unsafe fn read_from_port(port: u16) -> Self;
}Expand description
A helper trait that implements the read port operation.
On x86, I/O ports operate on either u8 (via inb/outb), u16 (via inw/outw),
or u32 (via inl/outl). Therefore this trait is implemented for exactly these types.
Required Methods§
sourceunsafe fn read_from_port(port: u16) -> Self
unsafe fn read_from_port(port: u16) -> Self
Reads a Self value from the given port.
Safety
This function is unsafe because the I/O port could have side effects that violate memory safety.
Object Safety§
This trait is not object safe.
