eBPF program type variants. Based off of kernel header’s enum bpf_prog_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`

`SocketFilter`

`Kprobe`

`SchedCls`

`SchedAct`

`Tracepoint`

`Xdp`

`PerfEvent`

`CgroupSkb`

`CgroupSock`

`LwtIn`

`LwtOut`

`LwtXmit`

`SockOps`

`SkSkb`

`CgroupDevice`

`SkMsg`

`RawTracepoint`

`CgroupSockAddr`

`LwtSeg6local`

`LircMode2`

`SkReuseport`

`FlowDissector`

`CgroupSysctl`

`RawTracepointWritable`

`CgroupSockopt`

`Tracing`

`Syscall`

Implementations

impl ProgramType

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

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

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

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

pub fn probe_helper(&self, helper: BpfHelper) -> Result<bool, Error>

Determines if the eBPF program helper function can be used my supported program types.

Note: Due to libbpf’s libbpf_probe_bpf_helper, this may return Ok(true) for unsupported program types. It is recommended to verify if the program type is supported before probing for helper support.

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

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

Note: Skips ProgramType::Unspec since it’s an invalid program type
