Expand description

A defined flags value that may be named or unnamed.

Implementations§

Source§

impl<B> Flag<B>

Source

pub const fn new(name: &'static str, value: B) -> Self

Define a flag.

If name is non-empty then the flag is named, otherwise it’s unnamed.

Source

pub const fn name(&self) -> &'static str

Get the name of this flag.

If the flag is unnamed then the returned string will be empty.

Source

pub const fn value(&self) -> &B

Get the flags value of this flag.

Source

pub const fn is_named(&self) -> bool

Whether the flag is named.

If Flag::name returns a non-empty string then this method will return true.

Source

pub const fn is_unnamed(&self) -> bool

Whether the flag is unnamed.

If Flag::name returns a non-empty string then this method will return false.
