Sorting things

2 declarations

valuepartitionOptReq

:: Eq a
=> [a]
What do we have available
-> [a]
Optional desired elements
-> [a]
Required desired elements
-> ([a], Either [a] [a])
(Missing optional elements, Either (missing required elements) or (all required elements and as many optional elements as possible)

From a list of things, take all the required things and as many optional things as possible.

valuepartitionOptReqIO

:: (Show a, Eq a, MonadIO m)
=> String
What are we sorting (Used for a debug message)
-> [a]
What do we have available
-> [a]
Optional desired elements
-> [a]
Required desired elements
-> m ([a], [a])
All the required elements and as many optional elements as possible, as well as the missing optional elements.

Will throw an 'IOError in the case of missing things. Details on missing things will be reported in stderr.

This is useful in dealing with layers and extensions.

2 declarations

valueshowBits :: (Show a, FiniteBits a) => a -> String

Show valies as a union of their individual bits

Example1 expression

>>> showBits @Int 5"1 .|. 4"

Example1 expression

>>> showBits @Int 0"zeroBits"

Example2 expressions

>>> import Vulkan.Core10.Enums.QueueFlagBits>>> showBits (QUEUE_COMPUTE_BIT .|. QUEUE_GRAPHICS_BIT)"QUEUE_GRAPHICS_BIT .|. QUEUE_COMPUTE_BIT"

value(.&&.) :: Bits a => a -> a -> Bool

Check if the intersection of bits is non-zero
