==================== mutex lock.

BoolComparator compare a with b -1 , if a < b 0 , if a == b 1 , if a > b.

Clear removes all entries from m, leaving it empty.

Clone returns a copy of m.

Complex128Comparator compare a with b -1 , if a < b 0 , if a == b 1 , if a > b.

Complex64Comparator compare a with b -1 , if a < b 0 , if a == b 1 , if a > b.

Copy copies all key/value pairs in src adding them to dst.

DeleteFunc deletes any key/value pairs from m for which del returns true.

Equal reports whether two maps contain the same key/value pairs.

EqualFunc is like Equal, but compares values using eq.

Float32Comparator compare a with b -1 , if a < b 0 , if a == b 1 , if a > b.

Float64Comparator compare a with b -1 , if a < b 0 , if a == b 1 , if a > b.

HashMapWithSafe is used to set a map goroutine-safe Note that iterators are not goroutine safe, and it is useless to turn on the setting option here.

Int32Comparator compare a with b -1 , if a < b 0 , if a == b 1 , if a > b.

Int64Comparator compare a with b -1 , if a < b 0 , if a == b 1 , if a > b.

Int8Comparator compare a with b -1 , if a < b 0 , if a == b 1 , if a > b.

IntComparator compare a with b -1 , if a < b 0 , if a == b 1 , if a > b.

Keys returns the keys of the map m.

New creates a new map.

Reverse returns a comparator reverse to cmp.

StringComparator compare a with b -1 , if a < b 0 , if a == b 1 , if a > b.

UintComparator compare a with b -1 , if a < b 0 , if a == b 1 , if a > b.

UintptrComparator compare a with b -1 , if a < b 0 , if a == b 1 , if a > b.

Values returns the values of the map m.

HashMap uses RbTress for internal data structure, and every key can must bee unique.

InvalidLocker is a fake locker.

==================== Locker.

Options holds Map's options.

普通锁.

读写锁.

Comparator Should return a number: -1 , if a < b 0 , if a == b 1 , if a > b.

Option is a function type used to set Options.
