Struct MatchFailure 

pub struct MatchFailure {
    pub failed_at: usize,
    pub expected_next: Vec<String>,
    pub found: Option<String>,
}

Match failure: the observed sequence does not satisfy the expression. failed_at is the index into the observed sequence (== its length when the body ended too early); expected_next lists the display forms of the terminals legal at that position; found is the display form of the offending block (None at end-of-body).

Fields

failed_at: usize

expected_next: Vec<String>

found: Option<String>
