Required Methods§
sourcefn is_type_64(&self) -> bool
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.
fn e_ident(&self) -> &Ident
fn e_type(&self, endian: Self::Endian) -> u16
fn e_machine(&self, endian: Self::Endian) -> u16
fn e_version(&self, endian: Self::Endian) -> u32
fn e_entry(&self, endian: Self::Endian) -> Self::Word
fn e_phoff(&self, endian: Self::Endian) -> Self::Word
fn e_shoff(&self, endian: Self::Endian) -> Self::Word
fn e_flags(&self, endian: Self::Endian) -> u32
fn e_ehsize(&self, endian: Self::Endian) -> u16
fn e_phentsize(&self, endian: Self::Endian) -> u16
fn e_phnum(&self, endian: Self::Endian) -> u16
fn e_shentsize(&self, endian: Self::Endian) -> u16
fn e_shnum(&self, endian: Self::Endian) -> u16
fn e_shstrndx(&self, endian: Self::Endian) -> u16
Provided Methods§
sourcefn parse<'data, R: ReadRef<'data>>(data: R) -> Result<&'data Self>
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.
sourcefn is_supported(&self) -> bool
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.
fn is_class_32(&self) -> bool
fn is_class_64(&self) -> bool
fn is_little_endian(&self) -> bool
fn is_big_endian(&self) -> bool
fn endian(&self) -> Result<Self::Endian>
sourcefn section_0<'data, R: ReadRef<'data>>(
&self,
endian: Self::Endian,
data: R
) -> Result<Option<&'data Self::SectionHeader>>
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.
sourcefn phnum<'data, R: ReadRef<'data>>(
&self,
endian: Self::Endian,
data: R
) -> Result<usize>
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.
sourcefn shnum<'data, R: ReadRef<'data>>(
&self,
endian: Self::Endian,
data: R
) -> Result<usize>
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.
sourcefn shstrndx<'data, R: ReadRef<'data>>(
&self,
endian: Self::Endian,
data: R
) -> Result<u32>
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).
sourcefn program_headers<'data, R: ReadRef<'data>>(
&self,
endian: Self::Endian,
data: R
) -> Result<&'data [Self::ProgramHeader]>
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.
sourcefn section_headers<'data, R: ReadRef<'data>>(
&self,
endian: Self::Endian,
data: R
) -> Result<&'data [Self::SectionHeader]>
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.
sourcefn section_strings<'data, R: ReadRef<'data>>(
&self,
endian: Self::Endian,
data: R,
sections: &[Self::SectionHeader]
) -> Result<StringTable<'data, R>>
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.
sourcefn sections<'data, R: ReadRef<'data>>(
&self,
endian: Self::Endian,
data: R
) -> Result<SectionTable<'data, Self, R>>
fn sections<'data, R: ReadRef<'data>>( &self, endian: Self::Endian, data: R ) -> Result<SectionTable<'data, Self, R>>
Return the section table.
sourcefn is_mips64el(&self, endian: Self::Endian) -> bool
fn is_mips64el(&self, endian: Self::Endian) -> bool
Returns whether this is a mips64el elf file.
