eBPF map type variants. Based off of kernel header’s enum bpf_map_type

Variants (Non-exhaustive)

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

`Unspec`

`Hash`

`Array`

`ProgArray`

`PerfEventArray`

`PerCpuHash`

`PerCpuArray`

`StackTrace`

`CgroupArray`

`LruHash`

`LruPerCpuHash`

`LpmTrie`

`ArrayOfMaps`

`HashOfMaps`

`DevMap`

`SockMap`

`CpuMap`

`XskMap`

`SockHash`

`CgroupStorage`

Implementations

impl MapType

pub fn name(&self) -> &'static str

Based off of bpftool’s map_type_name, returns a human-readable name of the eBPF map type.

pub fn probe(&self) -> Result<bool, Error>

Determines if the eBPF map type is supported on the current platform

pub fn iter() -> impl Iterator<Item = MapType>

Returns an ordered iterator over the MapType variants. The order is determined by the kernel header’s enum values.

Note: Skips MapType::Unspec since it’s an invalid map type
