Struct SheetAnchor 

pub struct SheetAnchor {
    pub view: String,
    pub kind: String,
    pub solid: String,
    pub vertex: u64,
    pub edge: String,
    pub fraction: f64,
}

A parsed anchor reference.

Fields

view: String

The PLACED VIEW’s id (SV2) — which projection the point belongs to.

kind: String

VERTEX, EDGE or CIRCLE.

solid: String

The solid the geometry belongs to.

vertex: u64

A display vertex’s topology id (VERTEX).

edge: String

The kernel edge name (EDGE, CIRCLE).

fraction: f64

Arc-length fraction along the edge (EDGE): 0 and 1 are its ends, 0.5 its midpoint.

Implementations

impl SheetAnchor

pub fn vertex(view: &str, solid: &str, topo_id: u64) -> SheetAnchor

pub fn edge(view: &str, solid: &str, edge: &str, fraction: f64) -> SheetAnchor

pub fn circle(view: &str, solid: &str, edge: &str) -> SheetAnchor

pub fn to_ref(&self) -> String

The reference string: {placement}:{kind}:{solid}#{entity}, with an edge’s fraction after an @.

The two separators are chosen so the parse cannot be ambiguous: a kernel edge name carries | and [n] but never a # or an @, and the placement id and the kind are this module’s own vocabulary.

pub fn parse(text: &str) -> Result<SheetAnchor, String>

Parse a reference string, or say what is wrong with it.
