ParameterTokenExtensions
static
Keyword-matching helpers for modifier/rule parameter tokens (equality lives in StringExtensions), so parsers never hand-roll StringComparison boilerplate.
public static bool IsPrefixOf(this ReadOnlySpan<char> token, ReadOnlySpan<char> word)True when token is a non-empty case-insensitive prefix of word — so dot matches dotted. Empty never matches; use for abbreviated keywords.
public static bool AsBool(this ReadOnlySpan<char> token, bool defaultValue = false)Parses a boolean keyword by prefix (t/true/yes/on/1 → true; f/false/no/off/0 → false), preferring true on an ambiguous prefix. Unmatched → defaultValue.
