This page tries to list all the symbols that are available from thestandard library in the namespacestd. The symbols are written as follows:

• Function names with().
• Templates with<>.

Symbols fromstd's sub-namespaces (e.g.chrono) are not listed here, but the namespace names (prepended with the icon ▶) are the links to the corresponding pages.

Macro symbols,exposition-only symbols andsymbols removed from the standard library are listed in separated pages.
