Struct VersionIndex

pub struct VersionIndex(pub u16);

The special GNU extension section .gnu.version has a section type of SHT_GNU_VERSYM. This section shall have the same number of entries as the Dynamic Symbol Table in the .dynsym section. The .gnu.version section shall contain an array of elements of type Elfxx_Half (both of which are 16-bit unsigned integers).

The .gnu.version section and VersionIndex values act as a lookup table for specifying the version defined for or required by the corresponding symbol in the Dynamic Symbol Table.

For example, the symbol at index N in the .dynsym Symbol Table will have a VersionIndex value located in the versym table at .gnu.version[N] which identifies structures in the .gnu.version_d and .gnu.version_r sections. These values are located in identifiers provided by the the vna_other member of the VerNeedAux structure or the vd_ndx member of the VerDef structure.

Implementations

impl VersionIndex

pub fn index(&self) -> u16

pub fn is_local(&self) -> bool

pub fn is_global(&self) -> bool

pub fn is_hidden(&self) -> bool

Trait Implementations

impl Debug for VersionIndex

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

Formats the value using the given formatter.

impl ParseAt for VersionIndex

fn parse_at<E: EndianParse>( endian: E, _class: Class, offset: &mut usize, data: &[u8], ) -> Result<Self, ParseError>

Parse this type by using the given endian-awareness and ELF class layout. This is generic on EndianParse in order to allow users to optimize for their expectations of data layout. See EndianParse for more details.

fn size_for(_class: Class) -> usize

Returns the expected size of the type being parsed for the given ELF class

fn validate_entsize(class: Class, entsize: usize) -> Result<usize, ParseError>

Checks whether the given entsize matches what we need to parse this type

impl PartialEq for VersionIndex

fn eq(&self, other: &VersionIndex) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
