FrameInitResult

Type Alias FrameInitResult 

pub type FrameInitResult<'a, F> = ItemOrResult<&'a mut F, <F as FrameTr>::FrameResult>;
Expand description

Type alias for frame init result

Aliased Type§

pub enum FrameInitResult<'a, F> {
    Item(&'a mut F),
    Result(<F as FrameTr>::FrameResult),
}

Variants§

§

Item(&'a mut F)

Contains an item that needs further processing.

§

Result(<F as FrameTr>::FrameResult)

Contains a final result.

Layout§

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.

Implementations

§

impl<ITEM, RES> ItemOrResult<ITEM, RES>

pub fn is_result(&self) -> bool

Returns true if this is a result variant.

pub fn is_item(&self) -> bool

Returns true if this is an item variant.

§

impl<ITEM, RES> ItemOrResult<ITEM, RES>

pub fn map_frame<OITEM>( self, f: impl FnOnce(ITEM) -> OITEM, ) -> ItemOrResult<OITEM, RES>

Maps the item variant using the provided function, leaving results unchanged.

pub fn map_result<ORES>( self, f: impl FnOnce(RES) -> ORES, ) -> ItemOrResult<ITEM, ORES>

Maps the result variant using the provided function, leaving items unchanged.
