Struct RuleOptions 

pub struct RuleOptions {
    pub finish: bool,
    pub maxmul: usize,
    pub include: String,
    pub exclude: String,
    pub start: String,
    pub history: Option<usize>,
}

Fields

finish: bool

The grammar’s end-of-source switch (default true). jsonic’s @finish reads it: an unterminated structure is closed at the end of the source when it is true and refused with end_of_source when it is false. The engine stores, merges and serializes it for the grammar and does not read it: trailing content is an error either way.

maxmul: usize

include: String

exclude: String

start: String

history: Option<usize>

How many predecessor snapshots a rule can reach through prev: the prev_rule chain a replace or a push links is cut past this many links, so a sequence’s iterations are not all kept until its container closes. None keeps every link, which is the canonical behaviour and the default (doc/rule-history-bound.md). Read as 1 to MAX_RULE_HISTORY: Some(0) as 1, a larger value as the cap.
