Struct DocumentExtension 

#[non_exhaustive]
pub struct DocumentExtension {
    pub schema_version: u16,
    pub clean_md_sha256: [u8; 32],
    pub layout_json_sha256: [u8; 32],
    pub report_json_sha256: [u8; 32],
    pub preview_png_sha256: Option<[u8; 32]>,

    pub clean_spans: Vec<EmittedTokenSpan>,
    pub codec_audit: Vec<CodecAuditRow>,
}

Signed document-context metadata carried inside a session snapshot envelope.

This extension is the v0.7 bridge for gaze-document: it is safe to serialize inside the owner-only snapshot envelope, while agent-facing files keep using non-sensitive mirrors. The single schema_version is bundle-level; sub-files do not carry independent schema versions.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

schema_version: u16

Bundle-level schema version shared by clean, layout, preview, report, and manifest files.

clean_md_sha256: [u8; 32]

SHA-256 of clean.md NFC-normalized bytes.

layout_json_sha256: [u8; 32]

SHA-256 of canonical layout.json bytes.

report_json_sha256: [u8; 32]

SHA-256 of canonical report.json bytes.

preview_png_sha256: Option<[u8; 32]>

SHA-256 of preview-redacted.png bytes when a preview is present.

page_count: u32

Page count reported for the source document.

audit_session_id: String

Audit session id mirrored from the writing session for cross-pane correlation.

clean_spans: Vec<EmittedTokenSpan>

Signed clean.md byte spans for every emitted token.

codec_audit: Vec<CodecAuditRow>

Codec audit rows for the decode path that produced this document extension.

Implementations

impl DocumentExtension

pub fn builder(schema_version: u16) -> DocumentExtensionBuilder

Starts a document extension builder for one bundle schema version.

Trait Implementations

impl Clone for DocumentExtension

fn clone(&self) -> DocumentExtension

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DocumentExtension

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DocumentExtension

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DocumentExtension

fn eq(&self, other: &DocumentExtension) -> 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 DocumentExtension

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
