In the call graph viewer below, each node
|
|
is a function belonging to this package
|
|
and its children are the functions it
|
|
calls—perhaps dynamically.
|
|
</p>
|
|
<p>
|
|
The root nodes are the entry points of the
|
|
package: functions that may be called from
|
|
outside the package.
|
|
There may be non-exported or anonymous
|
|
functions among them if they are called
|
|
dynamically from another package.
|
|
</p>
|
|
<p>
|
|
Click a node to visit that function's source code.
|
|
From there you can visit its callers by
|
|
clicking its declaring <code>func</code>
|
|
token.
|
|
</p>
|
|
<p>
|
|
Functions may be omitted if they were
|
|
determined to be unreachable in the
|
|
particular programs or tests that were
|
|
analyzed.

Decode returns the Unicode code point sequence represented
|
|
by the UTF-16 encoding s.

<p>
|
|
DecodeRune returns the UTF-16 decoding of a surrogate pair.
|
|
If the pair is not a valid UTF-16 surrogate pair, DecodeRune returns
|
|
the Unicode replacement code point U+FFFD.

<pre>func EncodeRune(r <a href="../../builtin/index.html#rune">rune</a>) (r1, r2 <a href="../../builtin/index.html#rune">rune</a>)</pre>
|
|
<p>
|
|
EncodeRune returns the UTF-16 surrogate pair r1, r2 for the given rune.
|
|
If the rune is not a valid Unicode code point or does not need encoding,
|
|
EncodeRune returns U+FFFD, U+FFFD.
