Everything elfpak needs to know about a single ELF object.

Fields

path: PathBuf

Path the metadata was read from (host path, not logical rootfs path).

architecture: Architecture

e_machine: u16

Raw e_machine, kept so diagnostics can name what was actually found even for architectures Machine does not model.

object_type: ObjectType

interpreter: Option<PathBuf>

needed: Vec<String>

soname: Option<String>

rpath: Vec<String>

runpath: Vec<String>

has_runpath: bool

Whether the object has a DT_RUNPATH tag, even if its value is empty.

nodeflib: bool

DF_1_NODEFLIB: skip default library search directories.

origin_flag: bool

DF_1_ORIGIN / DF_ORIGIN: object expects $ORIGIN processing.

is_dynamic: bool

dlopen_references: Vec<String>

References to dlopen-family functions, which static analysis cannot follow.

size: u64

Implementations

impl ElfMetadata

pub fn parse_file(path: &Path) -> Result<ElfMetadata>

pub fn looks_like_elf(bytes: &[u8]) -> bool

Cheap check used to decide whether a candidate file is worth parsing.

pub fn parse_bytes(path: &Path, bytes: &[u8]) -> Result<ElfMetadata>

pub fn runpath_is_authoritative(&self) -> bool

Effective search list contributed by this object: DT_RUNPATH wins over DT_RPATH, exactly like the glibc loader.

Trait Implementations

impl Clone for ElfMetadata

fn clone(&self) -> ElfMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ElfMetadata

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

Formats the value using the given formatter.
