Struct PrevParseInfo 

pub struct PrevParseInfo {
    pub tokens: Vec<PrevToken>,
    pub had_errors: bool,
}

Information from a previous parse needed for incremental re-parsing.

Fields

tokens: Vec<PrevToken>

had_errors: bool

Whether the previous parse produced any errors. When true, stored bracket depths are not used for conflict classification (they may be misleading due to error-recovery changing the grammar context), so fingerprint conflicts are treated as free-pass rather than +50 role conflicts.
