std::runtime::globals

Source: std/runtime/globals.slk

This is the exact canonical documentation page for std::runtime::globals.

Role#

std::runtime::globals defines the replaceable standard-library prelude. When the standard library is enabled, the compiler loads this module on demand when user source refers to one of its aliases. Its module-scope using declarations make their target types and interfaces available without an explicit import.

Prelude aliases are transparent during checking and generic monomorphization. For example, the shipped using Result = std::result::Result; permits Result(int, Error) with the same generic template, arity, and semantics as the fully qualified target.

• The shipped source for this module is std/runtime/globals.slk.
• The canonical module name is std::runtime::globals.
• Alternative standard-library roots may replace the aliases by shipping a compatible module at the same canonical name.
