Functions

func Parse

func Parse(v string) (int32, error)

Parse parses a string as base 10 int32.

func Ptr

func Ptr(v int32) *int32

Ptr returns a pointer to the value.

func PtrDefToNil

func PtrDefToNil(v int32, def int32) *int32

PtrDefToNil returns a pointer to the value, or nil if "def".

func PtrZeroToNil

func PtrZeroToNil(v int32) *int32

PtrZeroToNil returns a pointer to the value, or nil if 0.

func Val

func Val(v *int32) int32

Val returns the pointer value, defaulting to zero if nil.

func ValDef

func (m Map) Clone() Map

Clone the Map.

func (Map) Filter

func (m Map) Filter(p PredicateFunc) Map

Filter the Map to a copy using the given PredicateFunc (if p(v) = true, the value is copied, otherwise skipped).

func (Map) ForEach

func (m Map) ForEach(r ReceiveFunc)

func (Map) ToSlice

func (m Map) ToSlice() Slice

ToSlice converts the Map to a Slice.

type PredicateFunc

type PredicateFunc func(int32) bool

PredicateFunc describes a function that evaluates values of type int32.

func And

func And(ps ...PredicateFunc) PredicateFunc

And performs a lazy logical AND using the given PredicateFunc(s). Always returns true if len(ps) = 0.

func Eq

func Eq(eq int32) PredicateFunc
