Struct Rule 

pub struct Rule {
    pub cell: Face,
    pub base: Base,
    pub added: Vec<String>,
    pub removed: Vec<String>,
}

One neighbour that keeps a block: the neighbour across cell is in base, or is one of added, and is not one of removed.

Fields

cell: Face

The direction from the block to the neighbour this rule reads.

base: Base

The base set.

added: Vec<String>

States the jar keeps the block beside beyond the base, as table rows (minecraft:block or minecraft:block[k=v,…]).

removed: Vec<String>

States of the base the jar does not keep it beside.

Implementations

impl Rule

pub fn holds(&self, neighbour: &str) -> bool

Whether neighbour, the block across Rule::cell, keeps the block.

pub fn describe(&self) -> String

What the rule asks of its neighbour, as a verb phrase for a message (“give a full (sturdy) south face”, “be one of …”): the base, then the states it adds — listed whole up to a dozen, counted beyond.
