Struct Blockage 

pub struct Blockage {
    pub source: NodeId,
    pub why: StopCause,
    pub reaches: Vec<NodeId>,
}

One cause and everything waiting behind it.

reaches never contains source: a reader draws the source once, and a list that repeated it would make a single problem look like two.

Fields

source: NodeId

why: StopCause

reaches: Vec<NodeId>

Every node stuck because of this one, in reading order.

Implementations

impl Blockage

pub fn line(&self) -> String
