data Mutability

Is the memory mutable or not?

Constructors

Mutable

Memory cells are mutable

Immutable

Memory cells are immutable

Instances

Eq Mutability

Defined in Haskus.Memory.Property

Methods

(==) :: Mutability -> Mutability -> Bool

(/=) :: Mutability -> Mutability -> Bool

Show Mutability

Defined in Haskus.Memory.Property

Methods

showsPrec :: Int -> Mutability -> ShowS

show :: Mutability -> String

showList :: [Mutability] -> ShowS

data Heap

Allocation heap

Constructors

Internal

GHC heap

External

External heap

data Pinning

Is the buffer pinned into memory?

Constructors

Pinned

The buffer has a fixed associated memory address

NotPinned

The buffer contents can be freely moved to another address

Instances

Eq Pinning

Defined in Haskus.Memory.Property

Methods

(==) :: Pinning -> Pinning -> Bool

(/=) :: Pinning -> Pinning -> Bool

Show Pinning

Defined in Haskus.Memory.Property

Methods

showsPrec :: Int -> Pinning -> ShowS

show :: Pinning -> String

showList :: [Pinning] -> ShowS

data Finalization

Is the memory automatically garbage collected?

Constructors

Collected

Automatically collected by the garbage-collector

Finalized

Finalizers are run just before the garbage collector collects the referencing entity (buffer, pointer...). The memory used by the entity may be collected too (Internal heap), explicitly freed by a finalizer or not freed at all.

NotFinalized

The memory is not automatically freed and we can't attach finalizers to the buffer.

Instances

Eq Finalization

Defined in Haskus.Memory.Property

Methods

(==) :: Finalization -> Finalization -> Bool

(/=) :: Finalization -> Finalization -> Bool

Show Finalization

Defined in Haskus.Memory.Property

Methods

showsPrec :: Int -> Finalization -> ShowS

show :: Finalization -> String

showList :: [Finalization] -> ShowS
