source

type Sword: Into<i64>

source

type Endian: Endian

source

type ProgramHeader: ProgramHeader<Elf = Self, Endian = Self::Endian, Word = Self::Word>

Required Methods§

source

fn is_type_64(&self) -> bool

Return true if this type is a 64-bit header.

This is a property of the type, not a value in the header data.

source

fn is_type_64_sized() -> bool
where Self: Sized,

Return true if this type is a 64-bit header.

This is a property of the type, not a value in the header data.

This is the same as is_type_64, but is non-dispatchable.

source

fn e_ident(&self) -> &Ident

source

fn e_type(&self, endian: Self::Endian) -> u16

source

fn e_machine(&self, endian: Self::Endian) -> u16

source

fn e_version(&self, endian: Self::Endian) -> u32

source

fn e_entry(&self, endian: Self::Endian) -> Self::Word

source

fn e_phoff(&self, endian: Self::Endian) -> Self::Word

source

fn e_shoff(&self, endian: Self::Endian) -> Self::Word

source

fn e_flags(&self, endian: Self::Endian) -> u32

source

fn e_ehsize(&self, endian: Self::Endian) -> u16

source

fn e_phentsize(&self, endian: Self::Endian) -> u16

source

fn e_phnum(&self, endian: Self::Endian) -> u16

source

fn e_shentsize(&self, endian: Self::Endian) -> u16

source

fn e_shnum(&self, endian: Self::Endian) -> u16

source

fn e_shstrndx(&self, endian: Self::Endian) -> u16

Provided Methods§

source

fn parse<'data, R: ReadRef<'data>>(data: R) -> Result<&'data Self>

Read the file header.

Also checks that the ident field in the file header is a supported format.

source

fn is_supported(&self) -> bool

Check that the ident field in the file header is a supported format.

This checks the magic number, version, class, and endianness.

source

fn is_class_32(&self) -> bool

source

fn is_class_64(&self) -> bool

source

fn is_little_endian(&self) -> bool

source

fn is_big_endian(&self) -> bool

source

fn endian(&self) -> Result<Self::Endian>

source

fn section_0<'data, R: ReadRef<'data>>( &self, endian: Self::Endian, data: R, ) -> Result<Option<&'data Self::SectionHeader>>

Return the first section header, if present.

Section 0 is a special case because getting the section headers normally requires shnum, but shnum may be in the first section header.

source

fn phnum<'data, R: ReadRef<'data>>( &self, endian: Self::Endian, data: R, ) -> Result<usize>

Return the e_phnum field of the header. Handles extended values.

Returns Err for invalid values.

source

fn shnum<'data, R: ReadRef<'data>>( &self, endian: Self::Endian, data: R, ) -> Result<usize>

Return the e_shnum field of the header. Handles extended values.

Returns Err for invalid values.

source

fn shstrndx<'data, R: ReadRef<'data>>( &self, endian: Self::Endian, data: R, ) -> Result<u32>

Return the e_shstrndx field of the header. Handles extended values.

Returns Err for invalid values (including if the index is 0).

source

fn program_headers<'data, R: ReadRef<'data>>( &self, endian: Self::Endian, data: R, ) -> Result<&'data [Self::ProgramHeader]>

Return the slice of program headers.

Returns Ok(&[]) if there are no program headers. Returns Err for invalid values.

source

fn section_headers<'data, R: ReadRef<'data>>( &self, endian: Self::Endian, data: R, ) -> Result<&'data [Self::SectionHeader]>

Return the slice of section headers.

Returns Ok(&[]) if there are no section headers. Returns Err for invalid values.

source

fn section_strings<'data, R: ReadRef<'data>>( &self, endian: Self::Endian, data: R, sections: &[Self::SectionHeader], ) -> Result<StringTable<'data, R>>

Return the string table for the section headers.

source

fn sections<'data, R: ReadRef<'data>>( &self, endian: Self::Endian, data: R, ) -> Result<SectionTable<'data, Self, R>>

Return the section table.

source

fn is_mips64el(&self, endian: Self::Endian) -> bool

Returns whether this is a mips64el elf file.
