}

Parsed note header. Self-contained snapshot - the reader does not retain a reference into bucket bytes.

Fields

size: u32

Total note size in bytes (header + item descriptors + item data).

rrv_identifier: u32

RRV identifier the note was reached through. Local to one NSF.

file_identifier: Timedate

File identifier portion of the UNID (8 bytes).

note_identifier: Timedate

Note identifier portion of the UNID (8 bytes). Together with file_identifier this forms the 16-byte Universal Note ID (UNID) which is globally unique across replicas.

sequence_number: u32

Replication-sequence number. Increments on every modification.

sequence_time: Timedate

Replication-sequence time.

status_flags: u16

Status flags word.

note_class: u16

Note class (DOCUMENT / FORM / VIEW / ACL / etc). See class constants.

modification_time: Timedate

Most recent modification time. Operator-facing “when was this note last touched”.

number_of_note_items: u16

Number of items (fields) attached to this note. Each item has its own descriptor block immediately after the note header.

number_of_responses: u16

Number of response notes (replies to this note as a parent in a discussion-style database).

non_summary_data_identifier: u32

Identifier into the non-summary data area for items too large to fit in summary slots (rich-text bodies, attachments).

non_summary_data_size: u32

Size in bytes of the non-summary data area associated with this note.

access_time: Timedate

Most recent access time.

creation_time: Timedate

File-creation time (first-write timestamp).

parent_note_identifier: u32

NoteID of the parent (for response notes).

folder_reference_count: u32

Number of folders that reference this note.

folder_note_identifier: u32

NoteID of an associated folder (if any).

Implementations

impl NoteHeader

pub fn parse(bytes: &[u8]) -> Result<Self, NsfError>

Parse a note header from at least the first 100 bytes of a note record. Errors on signature mismatch or short input.

pub fn is_document(&self) -> bool

True if any DOCUMENT bit is set in the note class. User-visible emails, calendar entries, contacts, and custom-form documents all carry this bit.

pub fn is_design(&self) -> bool

True if the note carries any design-related class bit (FORM, VIEW, ICON, DESIGN, HELP, FILTER, FIELD, REPLFORMULA, PRIVATE).

pub fn unid_hex(&self) -> String

16-byte UNID (Universal Note Identifier) as a hex string. This is the globally-unique identifier that survives replication and compaction. Two replicas of the same logical note carry the same UNID.

Trait Implementations

impl Clone for NoteHeader

fn clone(&self) -> NoteHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NoteHeader

impl Debug for NoteHeader

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

Formats the value using the given formatter.

impl Eq for NoteHeader

impl PartialEq for NoteHeader

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