// ParsedSpecifier represents a parsed specifier, either
// - a non-bare specifier, parsed as a KURL as specced by
//   https://html.spec.whatwg.org/#resolve-a-module-specifier or
// - a bare specifier, stored as a String as-is.

// Non-import-maps cases:
// Bare specifiers should be rejected by callers as resolution errors.
// Then ParsedSpecifier represents the result of
// https://html.spec.whatwg.org/#resolve-a-module-specifier
// and behaves just like a KURL via GetUrl().

// Import-maps cases:
// In the import map spec, specifiers are handled mostly as strings,
// occasionally converted to/from URLs.
// In Blink, we pass ParsedSpecifier throughout the import map resolution,
// instead of passing String with occasionally converting to KURL.
// This avoid duplicated URL parsing.
