Struct object::read::elf::section::SectionTable

pub struct SectionTable<'data, Elf: FileHeader, R = &'data [u8]>
where
    R: ReadRef<'data>,
{
    sections: &'data [Elf::SectionHeader],
    strings: StringTable<'data, R>,
}

Also includes the string table used for the section names.

Returned by FileHeader::sections.

Fields

sections: &'data [Elf::SectionHeader]

strings: StringTable<'data, R>

Implementations

impl<'data, Elf: FileHeader, R: ReadRef<'data>> SectionTable<'data, Elf, R>

pub fn new( sections: &'data [Elf::SectionHeader], strings: StringTable<'data, R>, ) -> Self

Create a new section table.

pub fn iter(&self) -> Iter<'data, Elf::SectionHeader>

Iterate over the section headers.

This includes the null section at index 0, which you will usually need to skip.

pub fn enumerate( &self, ) -> impl Iterator<Item = (SectionIndex, &'data Elf::SectionHeader)>

Iterate over the section headers and their indices.

This includes the null section at index 0, which you will usually need to skip.

pub fn is_empty(&self) -> bool

Return true if the section table is empty.

pub fn len(&self) -> usize

The number of section headers.

pub fn section(&self, index: SectionIndex) -> Result<&'data Elf::SectionHeader>

Get the section header at the given index.

Returns an error for the null section at index 0.

pub fn section_by_name( &self, endian: Elf::Endian, name: &[u8], ) -> Option<(SectionIndex, &'data Elf::SectionHeader)>

Return the section header with the given name.

Ignores sections with invalid names.

pub fn section_name( &self, endian: Elf::Endian, section: &Elf::SectionHeader, ) -> Result<&'data [u8]>

Return the section name for the given section header.

pub fn strings( &self, endian: Elf::Endian, data: R, index: SectionIndex, ) -> Result<StringTable<'data, R>>

Return the string table at the given section index.

Returns an empty string table if the index is 0. Returns an error if the section is not a string table.

pub fn symbols( &self, endian: Elf::Endian, data: R, sh_type: u32, ) -> Result<SymbolTable<'data, Elf, R>>

Return the symbol table of the given section type.

Returns an empty symbol table if the symbol table does not exist.

pub fn symbol_table_by_index( &self, endian: Elf::Endian, data: R, index: SectionIndex, ) -> Result<SymbolTable<'data, Elf, R>>

Return the symbol table at the given section index.

Returns an error if the section is not a symbol table.

pub fn relocation_sections( &self, endian: Elf::Endian, symbol_section: SectionIndex, ) -> Result<RelocationSections>

Create a mapping from section index to associated relocation sections.

pub fn dynamic( &self, endian: Elf::Endian, data: R, ) -> Result<Option<(&'data [Elf::Dyn], SectionIndex)>>

Return the contents of a dynamic section.

Also returns the linked string table index.

Returns Ok(None) if there is no SHT_DYNAMIC section. Returns Err for invalid values.

pub fn hash_header( &self, endian: Elf::Endian, data: R, ) -> Result<Option<&'data HashHeader<Elf::Endian>>>

Return the header of a SysV hash section.

Returns Ok(None) if there is no SysV GNU hash section. Returns Err for invalid values.

pub fn hash( &self, endian: Elf::Endian, data: R, ) -> Result<Option<(HashTable<'data, Elf>, SectionIndex)>>

Return the contents of a SysV hash section.

Also returns the linked symbol table index.

Returns Ok(None) if there is no SysV hash section. Returns Err for invalid values.

pub fn gnu_hash_header( &self, endian: Elf::Endian, data: R, ) -> Result<Option<&'data GnuHashHeader<Elf::Endian>>>

Return the header of a GNU hash section.

Returns Ok(None) if there is no GNU hash section. Returns Err for invalid values.

pub fn gnu_hash( &self, endian: Elf::Endian, data: R, ) -> Result<Option<(GnuHashTable<'data, Elf>, SectionIndex)>>

Return the contents of a GNU hash section.

Also returns the linked symbol table index.

Returns Ok(None) if there is no GNU hash section. Returns Err for invalid values.

pub fn gnu_versym( &self, endian: Elf::Endian, data: R, ) -> Result<Option<(&'data [Versym<Elf::Endian>], SectionIndex)>>

Return the contents of a SHT_GNU_VERSYM section.

Also returns the linked symbol table index.

Returns Ok(None) if there is no SHT_GNU_VERSYM section. Returns Err for invalid values.

pub fn gnu_verdef( &self, endian: Elf::Endian, data: R, ) -> Result<Option<(VerdefIterator<'data, Elf>, SectionIndex)>>

Return the contents of a SHT_GNU_VERDEF section.

Also returns the linked string table index.

Returns Ok(None) if there is no SHT_GNU_VERDEF section. Returns Err for invalid values.

pub fn gnu_verneed( &self, endian: Elf::Endian, data: R, ) -> Result<Option<(VerneedIterator<'data, Elf>, SectionIndex)>>

Return the contents of a SHT_GNU_VERNEED section.

Also returns the linked string table index.
