Struct HelperSet 

pub struct HelperSet<C: EbpfProgramContext> { /* private fields */ }

Stores set of helpers for an eBPF program. The helpers are stored packed in a vector for fast access in the interpreter.

Implementations

impl<C: EbpfProgramContext> HelperSet<C>

pub fn new(iter: impl IntoIterator<Item = (u32, EbpfHelperImpl<C>)>) -> Self

pub fn get_index_by_id(&self, id: u32) -> Option<u32>

Looks up a helper by ID, returns helper index.

pub fn get_by_index(&self, index: u32) -> Option<&EbpfHelperImpl<C>>

Returns the helper with the specified index.

Trait Implementations

impl<C: EbpfProgramContext> Clone for HelperSet<C>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<C: EbpfProgramContext> Default for HelperSet<C>

fn default() -> Self

Returns the “default value” for a type.

impl<C: EbpfProgramContext> FromIterator<(u32, EbpfHelperImpl<C>)> for HelperSet<C>

fn from_iter<T>(iter: T) -> Self

where T: IntoIterator<Item = (u32, EbpfHelperImpl<C>)>,

Creates a value from an iterator.
