Assert.IsNot¶

Name	Mandatory	Description	Default	Type
`⬅️ Input`		The input can be of any type.		`Any`
`Output ➡️`		The output will be the input (passthrough).		`Any`
`Value`	No	The value to test against for equality.	`none`	`Any`
`Break`	No	If we should trigger a debug breakpoint on failure.	`false`	`Bool`

This assertion is used to check whether the input is different from a given value.

Details¶

Returns true if the input is not equal to the Value parameter and false otherwise. The shard also is type sensitive (e.g., 1 | IsNot(1.0) will return true).

If the Break parameter is set to false - logs an assertion validation error but continues running the programme.

Examples¶

Code

// :Break = `true`, assertion true
// => log no errors and dont abort program
8 | Assert.IsNot(16 Break: true)

Code

// :Break = `true`, assertion false
// => abort the program
8 | Maybe({
  Assert.IsNot(8 Break: true)
})

[error] Failed assertion IsNot, input: 8 not expected: 8
[warning] Maybe shard Ignored an error
    Assert failed - IsNot
    Unknown error

Code

// :Break = `false`, assertion true
// => log no errors and dont abort program
8 | Assert.IsNot(16 Break: false)

Code

// :Break = `false`, assertion false
// => log assertion error but dont abort program
8 | Maybe({
  Assert.IsNot(8 Break: false)
})
