Struct Map 

pub struct Map<'m, M, F> { /* private fields */ }

Helper type for PropMap::map. See that method for more information.

Trait Implementations

impl<'m, M: Debug, F: Debug> Debug for Map<'m, M, F>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'m, H, M, F, TargetT> PropMap<H> for Map<'m, M, F>

where H: Handle, M: PropMap<H>, M::Target: 'm, F: Fn(Value<M::Ret<'m>, M::Target>) -> TargetT,

type Target = TargetT

The owned prop type that this map maps to.

type Ret<'s> = <Map<'m, M, F> as PropMap<H>>::Target where Self: 's

Return type of Self::get: either Self::Target or &Self::Target.

fn get(&self, handle: H) -> Option<Value<Self::Ret<'_>, Self::Target>>

Returns the property associated with handle or None if no such property exists. For technical reasons, the returned value is wrapped in Value.

fn contains_handle(&self, handle: H) -> bool

Returns true if there is a property associated with handle, false otherwise.

fn map<F, TargetT>(&self, f: F) -> Map<'_, Self, F>

where Self: Sized, F: Fn(Value<Self::Ret<'_>, Self::Target>) -> TargetT,

Creates a new prop map that applies the given function to each element of the original map. Very similar to Iterator::map.
