Struct object::read::elf::VersionTable

pub struct VersionTable<'data, Elf: FileHeader> { /* private fields */ }

A table of version definitions and requirements.

It allows looking up the version information for a given symbol index.

This is derived from entries in the SHT_GNU_versym, SHT_GNU_verdef and SHT_GNU_verneed sections.

Implementations

impl<'data, Elf: FileHeader> VersionTable<'data, Elf>

pub fn parse<R: ReadRef<'data>>(
    endian: Elf::Endian,
    versyms: &'data [Versym<Elf::Endian>],
    verdefs: Option<VerdefIterator<'data, Elf>>,
    verneeds: Option<VerneedIterator<'data, Elf>>,
    strings: StringTable<'data, R>
) -> Result<Self>

Parse the version sections.

pub fn is_empty(&self) -> bool

Return true if the version table is empty.

pub fn version_index(&self, endian: Elf::Endian, index: usize) -> VersionIndex

Return version index for a given symbol index.

pub fn version(&self, index: VersionIndex) -> Result<Option<&Version<'data>>>

Return version information for a given symbol version index.

Returns Ok(None) for local and global versions. Returns Err(_) if index is invalid.

pub fn matches(
    &self,
    endian: Elf::Endian,
    index: usize,
    need: Option<&Version<'_>>
) -> bool

Return true if the given symbol index satisifies the requirements of need.

Returns false for any error.

Note: this function hasn’t been fully tested and is likely to be incomplete.
