Struct object::read::elf::VersionTable

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

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 elf::SHT_GNU_VERSYM, elf::SHT_GNU_VERDEF and elf::SHT_GNU_VERNEED sections.

Returned by SectionTable::versions.

Implementations§

source§

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

source

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.

source

pub fn is_empty(&self) -> bool

Return true if the version table is empty.

source

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

Return version index for a given symbol index.

source

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.

source

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

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

Returns false for any error.

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