Enum TagError 

pub enum TagError {
    Empty,
    TooLong {
        length: usize,
    },
    BadStart {
        character: char,
    },
    Illegal {
        position: usize,
        character: char,
    },
}

Why a name cannot be a tag. Positions are counted from one, the way a person counts the letters of the name they just typed.

Variants

Empty

Nothing was written.

TooLong

The name is longer than a tag may be.

Fields

length: usize

How many characters were written.

BadStart

The first character is not a letter, so the tag would not read as a name.

Fields

character: char

The character that was written first.

Illegal

A character a tag cannot hold.

Fields

position: usize

Which character it is, counted from one.

character: char

The character itself.
