    Description
    static int
    countRawHashes(String capture)
    Counts the number of hashes ('#') before a terminating quote ('"') in capture.
    static boolean
    isRawEnding(String capture, int rawHashCount)
    Determines if the specified capture starts with a quote ('"') and is followed by the specified number of hashes (plus possibly an excess number of hashes), indicating the end of a raw- or raw-byte- string.

  • Method Details

    • countRawHashes

      public static int countRawHashes(String capture)
      Counts the number of hashes ('#') before a terminating quote ('"') in capture.
      Parameters:
      capture - the Rust raw- or raw-byte-string initiator (e.g., "r##\"")
      Returns:
      the number of hashes counted

    • isRawEnding

      public static boolean isRawEnding(String capture, int rawHashCount)
      Determines if the specified capture starts with a quote ('"') and is followed by the specified number of hashes (plus possibly an excess number of hashes), indicating the end of a raw- or raw-byte- string.
      Parameters:
      capture - the possible Rust raw- or raw-byte-string ender (e.g., "\"####")
      rawHashCount - the number of required hashes in order to be considered "raw-ending"
      Returns:
      true if the capture is determined to be "raw-ending" or false otherwise (N.b., there may have been too many hashes captured, so any excess of yylength() minus one minus rawHashCount should be pushed back.
