Struct Legend 

pub struct Legend<T> {
    pub names: BTreeMap<char, String>,
    pub terrains: BTreeMap<char, T>,
}

A map’s legend: tile character → terrain id as written, and what each resolved to.

Fields

names: BTreeMap<char, String>

Character → terrain id, as written in the file.

terrains: BTreeMap<char, T>

Character → resolved terrain.

Implementations

impl<T: Copy + PartialEq> Legend<T>

pub fn resolve( names: BTreeMap<char, String>, terrain: impl Fn(&str) -> Option<T>, ) -> Option<Self>

Builds a legend from char → terrain id pairs, resolving each id with terrain; None if any id is unknown.

pub fn char_for(&self, t: T) -> Option<char>

The first (lowest) character standing for terrain t.
