Struct HeaderProvenance 

pub struct HeaderProvenance {
    pub version: u32,
    pub unclean_shutdown: bool,
    pub newline_check_intact: bool,
    pub uses_redundant_gd: bool,
    pub compressed: bool,
    pub has_markers: bool,
}

Provenance read from the 512-byte sparse header — fields other readers discard.

Fields

version: u32

Header format version (1, 2, or 3).

unclean_shutdown: bool

uncleanShutdown (byte 72) — the disk was not closed cleanly (crash / power-loss / live image): in-flight writes may be inconsistent.

newline_check_intact: bool

Newline-detection bytes (73..77) are exactly 0A 20 0D 0A. false ⇒ the binary was mangled by an ASCII-mode FTP transfer (which rewrites \r\n).

uses_redundant_gd: bool

Flag bit 0x2 — a redundant (secondary) grain directory is present.

compressed: bool

Flag bit 0x10000 — grains carry compressed data.

has_markers: bool

Flag bit 0x20000 — the stream carries metadata markers (streamOptimized).

Trait Implementations

impl Clone for HeaderProvenance

fn clone(&self) -> HeaderProvenance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HeaderProvenance

impl Debug for HeaderProvenance

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

Formats the value using the given formatter.

impl Eq for HeaderProvenance

impl PartialEq for HeaderProvenance

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