pub struct GnuHashTable<'data, Elf: FileHeader> { /* private fields */ }Expand description
A GNU symbol hash table in an ELF file.
Implementations
sourceimpl<'data, Elf: FileHeader> GnuHashTable<'data, Elf>
impl<'data, Elf: FileHeader> GnuHashTable<'data, Elf>
sourcepub fn parse(endian: Elf::Endian, data: &'data [u8]) -> Result<Self>
pub fn parse(endian: Elf::Endian, data: &'data [u8]) -> Result<Self>
Parse a GNU hash table.
data should be from a SHT_GNU_HASH section, or from a
segment pointed to via the DT_GNU_HASH entry.
The header is read at offset 0 in the given data.
The header does not contain a length field, and so all of data
will be used as the hash table values. It does not matter if this
is longer than needed, and this will often the case when accessing
the hash table via the DT_GNU_HASH entry.
sourcepub fn symbol_base(&self) -> u32
pub fn symbol_base(&self) -> u32
Return the symbol table index of the first symbol in the hash table.
sourcepub fn symbol_table_length(&self, endian: Elf::Endian) -> Option<u32>
pub fn symbol_table_length(&self, endian: Elf::Endian) -> Option<u32>
Determine the symbol table length by finding the last entry in the hash table.
Returns None if the hash table is empty or invalid.
sourcepub fn find<R: ReadRef<'data>>(
&self,
endian: Elf::Endian,
name: &[u8],
hash: u32,
version: Option<&Version<'_>>,
symbols: &SymbolTable<'data, Elf, R>,
versions: &VersionTable<'data, Elf>
) -> Option<(usize, &'data Elf::Sym)>
pub fn find<R: ReadRef<'data>>(
&self,
endian: Elf::Endian,
name: &[u8],
hash: u32,
version: Option<&Version<'_>>,
symbols: &SymbolTable<'data, Elf, R>,
versions: &VersionTable<'data, Elf>
) -> Option<(usize, &'data Elf::Sym)>
Use the hash table to find the symbol table entry with the given name, hash, and version.
