The macro that generates a bitmask and it's associated bit flags.

See the crate level docs for more info and examples.

Methods

• none - Create a new mask with all flags unset.
• all - Create a new mask with all flags set.
• set - Set a single flag if enum flag variant is passed or multiple if mask is passed.
• unset - Unset a single flag if enum flag variant is passed or multiple if mask is passed.
• toggle - Same as set/unset but always negates the flags (1 -> 0 and 0 -> 1).
• contains - Check if the mask contains a flag or a whole mask.
• intersects - Check if the mask intersects with a flag or a whole mask.
• is_all - Check if all flag variants are set.
• is_none - Check if all flag variants are unset.

Operators

• BitOr
• BitXor
• BitAnd
• BitOrAssign
• BitXorAssign
• BitAndAssign
• Not - Same as toggle but creates a new mask with the resulting value.

Misc

• From< enum > for struct
• Deref for struct
• Deref for enum
