Struct libbpf_rs::OpenProgram

pub struct OpenProgram { /* private fields */ }

Represents a parsed but not yet loaded BPF program.

This object exposes operations that need to happen before the program is loaded.

Implementations

impl OpenProgram

pub fn set_prog_type(&mut self, prog_type: ProgramType)

pub fn set_attach_type(&mut self, attach_type: ProgramAttachType)

pub fn set_ifindex(&mut self, idx: u32)

pub fn section(&self) -> &str

Name of the section this Program belongs to.

pub fn set_autoload(&mut self, autoload: bool) -> Result<()>

pub fn set_attach_target(
    &mut self,
    attach_prog_fd: i32,
    attach_func_name: Option<String>
) -> Result<()>

pub fn set_flags(&self, flags: u32) -> Result<()>

pub fn insn_cnt(&self) -> usize

Returns the number of instructions that form the program.

Note: Keep in mind, libbpf can modify the program’s instructions and consequently its instruction count, as it processes the BPF object file. So OpenProgram::insn_cnt and Program::insn_cnt may return different values.
