Struct OptionalHeader 

pub struct OptionalHeader {
    pub standard_fields: StandardFields,
    pub windows_fields: WindowsFields,
    pub data_directories: DataDirectories,
}

Unified 32/64-bit optional header (for PE32 and PE32+).

Optional header is the most important of the NT headers. Although it’s called “optional”, it’s actually required for PE image files.

It is meant to represent either

• IMAGE_OPTIONAL_HEADER32; or
• IMAGE_OPTIONAL_HEADER64.

Whether it’s 32 or 64-bit is determined by the StandardFields::magic and by the value CoffHeader::size_of_optional_header.

Position in PE binary

The optional header is located after CoffHeader and before section table.

Fields

standard_fields: StandardFields

Unified standard (COFF) fields. See StandardFields to learn more.

windows_fields: WindowsFields

Unified Windows fields. See WindowsFields to learn more.

data_directories: DataDirectories

Data directories. See DataDirectories to learn more.

Implementations

impl OptionalHeader

pub fn container(&self) -> Result<Container>

Returns the container type of the PE binary.

Trait Implementations

impl Clone for OptionalHeader

fn clone(&self) -> OptionalHeader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for OptionalHeader

impl Debug for OptionalHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for OptionalHeader

fn eq(&self, other: &OptionalHeader) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
