Type Alias ParsingResult<T>

Whereas ParsingError is thrown when parsing fails, e.g. in a fromString function, this type is returned from "defensive" functions like isValid.

type ParsingResult<T> = {
    invalidReason?: T;
    invalidReasonMessage?: string;
    valid: boolean;
}

Implementation - Serialization

invalidReason?: T

If valid is false, this will be a code explaining why parsing failed.

invalidReasonMessage?: string

If valid is false, this will be a string explaining why parsing failed.

valid: boolean

True if valid, false otherwise.
