Struct Bpf

pub struct Bpf {
    pub has_bpf_syscall: bool,
    pub program_types: HashMap<ProgramType, Result<bool, BpfError>>,
    pub map_types: HashMap<MapType, Result<bool, BpfError>>,
    pub helpers: HashMap<ProgramType, Vec<Result<BpfHelper, BpfError>>>,
}

Results for each eBPF detection technique

The determination of support for these features relies on the implementations provided by libbpf.

Fields

has_bpf_syscall: bool

Attempts to load a simple program without error to determine if syscall is available

program_types: HashMap<ProgramType, Result<bool, BpfError>>

For each program type, we determine definite support or propagate the resulting error to the client.

Internally, this relies on libbpf’s libbpf_probe_bpf_prog_type implementation which currently attempts to load a basic program of each type to determine support

map_types: HashMap<MapType, Result<bool, BpfError>>

For each program type, we determine definite support or propagate the resulting error to the client

Internally, this relies on libbpf’s libbpf_probe_bpf_map_type implementation which currently attempts to create a map of each type to determine support

helpers: HashMap<ProgramType, Vec<Result<BpfHelper, BpfError>>>

Returns a list of supported helpers (or error if probe fails) for each program type.

Note: If the program type is NOT supported, then the list will be empty. If the program type is supported but an error occurs on the individual helper probe, that error will be propagated to the list.

Trait Implementations

impl Debug for Bpf

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

Formats the value using the given formatter.
