Struct TitleBlock 

pub struct TitleBlock {
    pub name: String,
    pub top: BlockId,
}

The document’s own registers — a mechanical drawing’s title block, expected to grow fields (author, revision notes, …). The singleton exception: never created by an op, no id, no lifecycle — OpCodes::Document is update-only.

Fields

name: String

top: BlockId

The designated root of the single-canvas view; NULL = no top yet (an empty document). A register, not a convention, so two concurrent Wrap Tops converge on the later one’s root instead of leaving two.

Trait Implementations

impl Clone for TitleBlock

fn clone(&self) -> TitleBlock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TitleBlock

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

Formats the value using the given formatter.

impl Default for TitleBlock

fn default() -> TitleBlock

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TitleBlock

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Entity for TitleBlock

type Update = TitleBlockUpdate

type Id = ()

fn apply(&mut self, update: &Self::Update)

impl PartialEq for TitleBlock

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
