Struct shio::util::typemap::TypeMap

pub struct TypeMap<A: ?Sized = UnsafeAny> where
    A: UnsafeAnyExt,  { /* fields omitted */ }

Methods

impl TypeMap

fn new() -> TypeMap

Create a new, empty TypeMap.

impl<A: UnsafeAnyExt + ?Sized> TypeMap<A>

fn custom() -> TypeMap<A>

Create a new, empty TypeMap.

Can be used with any A parameter; new is specialized to get around the required type annotations when using this function.

fn put<K: Key>(&mut self, val: K::Value) -> Option<K::Value> where
    K::Value: Any + Implements<A>, 

Insert a value into the map with a specified key type.

fn get<K: Key>(&self) -> &K::Value where
    K::Value: Any + Implements<A>, 

Gets a value from the type map.

Panics

If there is no value in the request state of the given type.

fn try_get<K: Key>(&self) -> Option<&K::Value> where
    K::Value: Any + Implements<A>, 

Attempt to get a value from the type map.

fn has<K: Key>(&self) -> bool

Check if a key has an associated value stored in the map.

Trait Implementations

impl<A: Default + ?Sized> Default for TypeMap<A> where
    A: UnsafeAnyExt, 

fn default() -> TypeMap<A>

Returns the "default value" for a type.

impl<A: Debug + ?Sized> Debug for TypeMap<A> where
    A: UnsafeAnyExt, 

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.
