Struct TitleBlock 

pub struct TitleBlock {
    pub name: String,
    pub author: String,
    pub rev: Rev,
    pub date: Option<String>,
    pub from: Option<Provenance>,
}

What a title block states about a drawing. The strings are owned: the session hands the block a stamp rather than a borrow of itself, so the same stamp can be built where the document index is borrowed — and asked for by a test, or carried into an export.

Fields

name: String

What the document calls itself — the name in the window title, and the one the printed sheet’s block carries.

author: String

The name this session’s commits are attributed to.

rev: Rev

The revision on the canvas — the current one, or the one the time machine is showing.

date: Option<String>

The date Self::rev was written, read off the log rather than off a clock, so an export of a rev says the same thing every time it is taken. None for a scratch session, whose log carries no wall times — and then the block simply has no Date row.

from: Option<Provenance>

Where this session’s document came from, when it was opened from an export rather than authored here. Advisory and session-only: it is never written into the log.

Implementations

impl TitleBlock

pub fn grid(&self, path: &[String]) -> Grid

The block’s cells for the level at path, named outermost first (see content_path::segments). The document root names no level of its own, so its path is spelled ROOT_PATH: a sheet always says where it is.
