Struct NpcBody 

pub struct NpcBody(pub NpcKind, pub Box<dyn FnMut() -> Body>);

A combination of an NpcKind (representing an outer species to generate), and a function that generates a fresh Body of a species that is part of that NpcKind each time it’s called. The reason things are done this way is that when parsing spawn strings, we’d like to be able to randomize features that haven’t already been specified; for instance, if no species is specified we should randomize species, while if a species is specified we can still randomize other attributes like gender or clothing.

TODO: Now that we return a closure, consider having the closure accept a source of randomness explicitly, rather than always using ThreadRng.

Implementations

impl NpcBody

pub fn from_str_with( s: &str, kind_to_body: fn(NpcKind) -> Body, ) -> Result<Self, ()>

If there is an exact name match for a body kind, call kind_to_body on it. Otherwise, if an explicit species is found, generate a random member of the species; otherwise, return Err(()).

Trait Implementations

impl FromStr for NpcBody

fn from_str(s: &str) -> Result<Self, Self::Err>

Get an NPC kind from a string. If a body kind is matched without an associated species, generate the species randomly within it; if an explicit species is found, generate a random member of the species; otherwise, return Err(()).

type Err = ()

The associated error which can be returned from parsing.
