SassString
A Sass string value.
Strings may be quoted.
SassString indexes
Sass models strings as a sequence of unicode scalars, not Swift’s primary view as a sequence of extended grapheme clusters. So any string index you receive through Sass applies to the unicode scalar view of the string.
Further, Sass models 1 as the index of the first scalar in the string, and count as the index of the last.
This class offers a scalarIndexFrom(sassIndex:) method to wrap up both parts of this
conversion, but offers only sympathy to users having to deal with the results.
SassString conforms to SequenceSequence via SassValue. This sequence is a singleton sequence
containing the string value, not a sequence of scalars.

func scalarIndexFrom(sassIndex: SassValue) -> String.UnicodeScalarIndex
func scalarIndexFrom(sassIndex: SassValue) -> String.UnicodeScalarIndex
Interpret a Sass string index.
Declaration

index |
A Sass value intended to be used as a string index. This must be an
integer between 1 and |
Throws
SassFunctionError if sassIndex is not an integer or out of range.
Misc
static func ==(lhs: SassString, rhs: SassString) -> Bool
static func ==(lhs: SassString, rhs: SassString) -> Bool
Two SassStrings are equal if they have the same text, whether or not either is quoted.
Declaration
public static func == (lhs: SassString, rhs: SassString) -> Boolfunc accept<V, R>(visitor: V) -> R
func accept<V, R>(visitor: V) -> R
Take part in the SassValueVisitor protocol.
Declaration
public override func accept<V, R>(visitor: V) throws -> R
where V: SassValueVisitor, R == V.ReturnTypevar description: String
