Parse the section name from the string table.

fn file_range(&self, endian: Self::Endian) -> Option<(u64, u64)>

Return the offset and size of the section in the file.

Returns None for sections that have no data in the file.

fn data<'data, R: ReadRef<'data>>( &self, endian: Self::Endian, data: R ) -> Result<&'data [u8]>

Return the section data.

Returns Ok(&[]) if the section has no data. Returns Err for invalid values.

fn data_as_array<'data, T: Pod, R: ReadRef<'data>>( &self, endian: Self::Endian, data: R ) -> Result<&'data [T]>

Return the section data as a slice of the given type.

Allows padding at the end of the data. Returns Ok(&[]) if the section has no data. Returns Err for invalid values, including bad alignment.

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

Return the strings in the section.
