Enum FileHeader 

#[non_exhaustive]
pub enum FileHeader {
    V2(FileHeaderV2),
    V3(FileHeaderV3),
}

FHDR chunk: patch file header with a version-specific body.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

V2(FileHeaderV2)

Version 2 header body.

V3(FileHeaderV3)

Version 3 header body.

Implementations

impl FileHeader

pub fn version(&self) -> u8

Returns the format version: 2 for V2 headers, 3 for V3 headers.

pub fn patch_type(&self) -> &[u8; 4]

Returns the 4-byte patch type tag (e.g. b"D000").

Trait Implementations

impl Clone for FileHeader

fn clone(&self) -> FileHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileHeader

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

Formats the value using the given formatter.

impl PartialEq for FileHeader

fn eq(&self, other: &FileHeader) -> 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.
