Report a validation failure

A validator returns the (possibly coerced) value on success, or the object built here on failure, so the happy path allocates nothing beyond the value itself. .is_bad() tells the two apart.

Usage

.fail(problems)

Arguments

problems

A list of {path, expected, got, hint} records.

Value

A list of problem records, of class typed_problems.

Examples

p <- rdantic:::.fail(list(list(path = "$x", expected = "int", got = "chr[1]")))
rdantic:::.is_bad(p)
#> [1] TRUE
