Struct SectionDirectoryEntry 

pub struct SectionDirectoryEntry {
    pub section_type: SectionType,
    pub version: u8,
    pub flags: SectionFlags,
    pub offset: u64,
    pub length: u64,
    pub checksum: u32,
}

A single entry in the container’s section directory.

Fixed 32-byte layout for on-disk storage:

Offset	Size	Field
0	4	section_type (u32 LE)
4	1	version (u8)
5	1	flags (packed byte)
6	2	reserved (zero)
8	8	offset (u64 LE, byte offset from file start)
16	8	length (u64 LE, byte length of section data)
24	4	checksum (u32 LE, CRC-32 of section data)
28	4	reserved (zero)

Fields

section_type: SectionType

Which section type this entry describes.

version: u8

Per-section format version (allows independent evolution).

flags: SectionFlags

Section flags (required, mmap-able).

offset: u64

Byte offset from file start where section data begins.

length: u64

Byte length of the section data.

checksum: u32

CRC-32 checksum of the section data.

Implementations

impl SectionDirectoryEntry

pub const SIZE: usize = 32

Size of a directory entry on disk (fixed 32 bytes).

Trait Implementations

impl Clone for SectionDirectoryEntry

fn clone(&self) -> SectionDirectoryEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SectionDirectoryEntry

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SectionDirectoryEntry

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SectionDirectoryEntry

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

impl Serialize for SectionDirectoryEntry

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
