Module bitflags::parser

Parsing flags from text.

Format and parse a flags value as text using the following grammar:

• Flags: (Whitespace Flag Whitespace)|*
• Flag: Name | Hex Number
• Name: The name of any defined flag
• Hex Number: 0x([0-9a-fA-F])*
• Whitespace: (\s)*

As an example, this is how Flags::A | Flags::B | 0x0c can be represented as text:

A | B | 0x0c

Alternatively, it could be represented without whitespace:

A|B|0x0C

Note that identifiers are case-sensitive, so the following is not equivalent:

a|b|0x0C
