Package ptr provides helper functions for working with pointers.

Index

• func From(ptr *T) T
• func FromWithDefault(ptr *T, fallback T) T
• func To(v T) *T

Functions

func From

func From[T any](ptr *T) T

From returns the value pointed to by ptr, or the zero value of T if ptr is nil.

Example usage:

isBlocking := ptr.From(opts.Blocking)

func FromWithDefault

func FromWithDefault[T any](ptr *T, fallback T) T

FromWithDefault returns the value pointed to by ptr, or the provided fallback if ptr is nil.

Example usage:

interval := ptr.FromWithDefault(myPtr, 5 * time.Second)

func To

func To[T any](v T) *T

To returns a pointer to the value passed in. This is to help with verbose code like:

blocking := true
opts.Blocking = &blocking

Example usage:

opts.Blocking = ptr.To(true)
