Types ¶
type IfCond ¶
type IfCond[T, R any] struct { // contains filtered or unexported fields }
IfCond is a if condition control flow structure.
Example ¶
package main
import (
"fmt"
"github.com/snowmerak/generics-for-go/v2/syntax/cond"
)
func main() {
a := cond.If(func(t int) bool {
return t == 0
}, func(t int) string {
return "zero"
}).ElseIf(func(i int) bool {
return i == 1
}, func(i int) string {
return "one"
}).Else(func(i int) string {
return "other"
})
fmt.Println(a.Run(0))
fmt.Println(a.Run(1))
fmt.Println(a.Run(2))
}
Output: zero one other
type SwitchCond ¶
type SwitchCond[T comparable, R any] struct { // contains filtered or unexported fields }
SwitchCond is a switch condition control flow structure.
Example ¶
package main
import (
"fmt"
"github.com/snowmerak/generics-for-go/v2/syntax/cond"
)
func main() {
a := cond.Switch[int, string]().Case(0, func(i int) string {
return "zero"
}).Case(1, func(i int) string {
return "one"
}).Default(func(i int) string {
return "other"
})
fmt.Println(a.Run(0))
fmt.Println(a.Run(1))
fmt.Println(a.Run(2))
}
Output: zero one other
Example (Result) ¶
package main
import (
"fmt"
"github.com/snowmerak/generics-for-go/v2/syntax/cond"
"github.com/snowmerak/generics-for-go/v2/types/result"
)
func main() {
result := result.OK(100)
resultCond := cond.Switch[bool, int]().Case(true, func(b bool) int {
return result.Unwrap()
}).Default(func(b bool) int {
return -99
})
fmt.Println(resultCond.Run(result.IsOK()))
}
Output: 100
func (*SwitchCond[T, R]) Case ¶
func (s *SwitchCond[T, R]) Case(value T, result func(T) R) *SwitchCond[T, R]
Case adds a new condition to the SwitchCond.
func (*SwitchCond[T, R]) Default ¶
func (s *SwitchCond[T, R]) Default(defaultElse func(T) R) *SwitchCond[T, R]
Default adds a default result function to the SwitchCond.
func (*SwitchCond[T, R]) Run ¶
func (s *SwitchCond[T, R]) Run(t T) (rs R)
Run runs the SwitchCond with given value.
