Struct Failure 

pub struct Failure {
    pub offset: usize,
    pub expected: String,
    pub reach: usize,
}

Where a text stops matching a template, and what was expected there.

Fields

offset: usize

The byte offset in the text where the fault is.

expected: String

What the template expected at the offset.

reach: usize

How far the text matches the template before it fails, which can lie past the fault: of two shapes, the text meant the one it follows furthest.
