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

Variants (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.

Implementations

impl ProgramType

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

Trait Implementations

impl Clone for ProgramType

fn clone(&self) -> ProgramType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProgramType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ProgramType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<ProgramType> for u32

fn from(enum_value: ProgramType) -> Self

Converts to this type from the input type.

impl Hash for ProgramType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ProgramType

fn eq(&self, other: &ProgramType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<u32> for ProgramType

type Error = TryFromPrimitiveError<ProgramType>

The type returned in the event of a conversion error.

fn try_from(number: u32) -> Result<Self, TryFromPrimitiveError<Self>>

Performs the conversion.

impl TryFromPrimitive for ProgramType

const NAME: &'static str = "ProgramType"

type Primitive = u32

fn try_from_primitive( number: Self::Primitive, ) -> Result<Self, TryFromPrimitiveError<Self>>

impl Copy for ProgramType

impl Eq for ProgramType

impl StructuralPartialEq for ProgramType
