Struct init_tree::TypeInitDef

pub struct TypeInitDef {
    pub id: fn() -> TypeId,
    pub deps: fn() -> &'static [TypeInitDef],
    pub init: fn(_: &mut HashMap<TypeId, Box<dyn Any>>) -> Box<dyn Any>,
    pub name: &'static str,
}

Largely an implementation detail. However you may need to create one of these if you're manually implementing Init.

Fields

id: fn() -> TypeId

deps: fn() -> &'static [TypeInitDef]

init: fn(_: &mut HashMap<TypeId, Box<dyn Any>>) -> Box<dyn Any>

name: &'static str

Methods

impl TypeInitDef

pub fn new(
    id: fn() -> TypeId,
    deps: fn() -> &'static [TypeInitDef],
    init: fn(_: &mut HashMap<TypeId, Box<dyn Any>>) -> Box<dyn Any>,
    name: &'static str
) -> Self

Creates a new instance of this type.

Arguments

id: The TypeId for the type this will be able to construct.

deps: A function returning the list of direct dependencies for the constructed type.

deep_deps: A function which will populate an empty vector with all dependencies for the constructed type. Called recursively on dependencies.

init: A function that retrieves the needed dependencies from a HashMap, initializes the type, and then returns the instance in a type erased Box.

name: The name of the type this constructs.

Trait Implementations

impl Clone for TypeInitDef

fn clone(&self) -> TypeInitDef
