Create a schema check fragment — schema

schema_check() creates a raw schema fragment with a check operator. The helper performs only lightweight structural validation; semantic validation of kind and check arguments is handled by schema_doc() and schema edit verbs.

Usage

schema_check(kind, ..., description = NULL)

Arguments

kind: Check kind string.
...: Additional named checkmate arguments stored inside check.
description: Optional node description.

Value

A raw schema fragment accepted by schema_doc() and schema edit verbs.

Examples

schema_check("string", min.chars = 1)
#> $check
#> $check$kind
#> [1] "string"
#> 
#> $check$min.chars
#> [1] 1
#> 
#> 
schema <- schema_doc(schema_check("string", min.chars = 1))
schema
#> {
#>   "check": {
#>     "kind": "string",
#>     "min.chars": 1
#>   }
#> }
