Struct SimpleKey 

#[non_exhaustive]
pub struct SimpleKey {
    pub possible: bool,
    pub required: bool,
    pub token_number: usize,
    pub mark: Mark,
}

This structure holds information about a potential simple key.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

possible: bool

Is a simple key possible?

required: bool

Is a simple key required?

token_number: usize

The number of the token.

mark: Mark

The position mark.
