Enum rxdp::MapValue[−][src]

pub enum MapValue<V> {
    Single(V),
    Multi(Vec<V>),
}

Return value from eBPF maps.

Variants

Single(V)

Result from cpu-shared maps.

Multi(Vec<V>)

Result from per-cpu maps.

Implementations

impl<V> MapValue<V>[src]

pub fn into_vec(self) -> Vec<V>[src]

Convert the map value into a Vec<V>:

use rxdp::MapValue;
assert_eq!(MapValue::Multi(vec![1u32]).into_vec(), vec![1u32]);
assert_eq!(MapValue::Single(1u32).into_vec(), vec![1u32]);

pub fn into_single(self) -> V[src]

Convert the map value into a V. For the Multi variant, this will take the first element of the Vec:

use rxdp::MapValue;
assert_eq!(MapValue::Multi(vec![1u32, 2u32]).into_single(), 1u32);
assert_eq!(MapValue::Single(1u32).into_single(), 1u32);

Panics

Panics if len of Vec in Multi is 0.
