Struct rasn_mib::ip::Forwarding

#[repr(transparent)]
pub struct Forwarding(pub Integer);

The indication of whether this entity is acting as an IP gateway in respect to the forwarding of datagrams received by, but not addressed to, this entity. IP gateways forward datagrams. IP hosts do not (except those source-routed via the host).

Note that for some managed nodes, this object may take on only a subset of the values possible. Accordingly, it is appropriate for an agent to return a badValue response if a management station attempts to change this object to an inappropriate value.

Tuple Fields

0: Integer

Panics if the exponent is negative or the modulus is zero.

Returns whether the bit in position bit is set, using the two’s complement for negative numbers

pub fn set_bit(&mut self, bit: u64, value: bool)

Sets or clears the bit in the given position, using the two’s complement for negative numbers

Note that setting/clearing a bit (for positive/negative numbers, respectively) greater than the current bit length, a reallocation may be needed to store the new digits
