Trait FlagsList 

pub trait FlagsList<'a> {
    // Required methods
    fn new(tags: Tags<'a>, placeholder: &'a str) -> Self;
    fn add(&mut self, tags: Tags<'a>, placeholder: &'a str);
}

Errors sometimes need to be able to refer to a group of flags, guaranteeing at least one. This trait allows the error type to express which container it wants to use.

Required Methods

fn new(tags: Tags<'a>, placeholder: &'a str) -> Self

Create a new FlagsList. Flags lists are guaranteed to include at least one flag, so this constructor includes that flag.

fn add(&mut self, tags: Tags<'a>, placeholder: &'a str)

Insert an additional flag into this set.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
