Non-Member Functions

Name

Description

Erases all elements of the set that satisfy the predicate.

Returns whether two sets differ in their elements.

Returns whether two sets contain the same elements.

Swaps the contents of two sets.

settings::freezeImmutables

Freezes immutable settings ‐ preventing subsequent mutation attempts. It's up to the caller to call this function after settings have been initialized.
