DecodeRuneInString is like DecodeRune but its input is a string. If s is
empty it returns (RuneError, 0). Otherwise, if the encoding is invalid, it
returns (RuneError, 1). Both are impossible results for correct, non-empty
UTF-8.

DecodeRune unpacks the first UTF-8 encoding in p and returns the rune and
its width in bytes. If p is empty it returns (RuneError, 0). Otherwise, if
the encoding is invalid, it returns (RuneError, 1). Both are impossible
results for correct, non-empty UTF-8.

DecodeLastRuneInString is like DecodeLastRune but its input is a string. If
s is empty it returns (RuneError, 0). Otherwise, if the encoding is invalid,
it returns (RuneError, 1). Both are impossible results for correct,
non-empty UTF-8.

DecodeLastRune unpacks the last UTF-8 encoding in p and returns the rune and
its width in bytes. If p is empty it returns (RuneError, 0). Otherwise, if
the encoding is invalid, it returns (RuneError, 1). Both are impossible
results for correct, non-empty UTF-8.

Functions starting with "Is" can be used to inspect which table of range a
rune belongs to. Note that runes may fit into more than one range.

ToUpper maps the rune to upper case.

ToTitle maps the rune to title case.

ToLower maps the rune to lower case.

To maps the rune to the specified case: UpperCase, LowerCase, or TitleCase.

SpecialCase represents language-specific case mappings such as Turkish.
Methods of SpecialCase customize (by overriding) the standard mappings.

SimpleFold iterates over Unicode code points equivalent under
the Unicode-defined simple case folding. Among the code points
equivalent to rune (including rune itself), SimpleFold returns the
smallest rune > r if one exists, or else the smallest rune >= 0.
If r is not a valid Unicode code point, Sim...

Truncate returns the result of rounding t down to a multiple of d (since the zero time).
If d <= 0, Truncate returns t stripped of any monotonic clock reading but otherwise unchanged.

Sub returns the duration t-u. If the result exceeds the maximum (or minimum)
value that can be stored in a Duration, the maximum (or minimum) duration
will be returned.
To compute t-d for a duration d, use t.Add(-d).

String returns the time formatted using the format string

Round returns the result of rounding t to the nearest multiple of d (since the zero time).
The rounding behavior for halfway values is to round up.
If d <= 0, Round returns t stripped of any monotonic clock reading but otherwise unchanged.

Format returns a textual representation of the time value formatted
according to layout, which defines the format by showing how the reference
time, defined to be

Equal reports whether t and u represent the same time instant.
Two times can be equal even if they are in different locations.
For example, 6:00 +0200 CEST and 4:00 UTC are Equal.
See the documentation on the Time type for the pitfalls of using == with
Time values; most code should use Equal instead...

Day returns the day of the month specified by t.

Date returns the year, month, and day in which t occurs.

Before reports whether the time instant t is before u.

After reports whether the time instant t is after u.

AddDate returns the time corresponding to adding the
given number of years, months, and days to t.
For example, AddDate(-1, 2, 3) applied to January 1, 2011
returns March 4, 2010.

Add returns the time t+d.

Tick is a convenience wrapper for NewTicker providing access to the ticking
channel only. While Tick is useful for clients that have no need to shut down
the Ticker, be aware that without a way to shut it down the underlying
Ticker cannot be recovered by the garbage collector; it "leaks".
Unlike New...

ParseDuration parses a duration string.
A duration string is a possibly signed sequence of
decimal numbers, each with optional fraction and a unit suffix,
such as "300ms", "-1.5h" or "2h45m".
Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h".
