Struct FeatureParseOptions 

pub struct FeatureParseOptions {
    pub start_rule: Option<String>,
    pub max_depth: Option<usize>,

}

The limits and policies of a parse. Every field left None keeps the value the parser was compiled with, and then the default.

Fields

start_rule: Option<String>

The rule to parse from instead of the grammar’s start rule.

max_depth: Option<usize>

The bound on nested rule calls (default 1000).

step_limit: Option<usize>

The bound on evaluation steps (default 100000 + 1000 * input length, twice that with error recovery).

memo_limit: Option<usize>

The bound on memoized rule calls (default 1000000).

memory_limit: Option<usize>

The memory budget of the whole parse, its runs, repair rounds and embedded languages included, in memo cells: one per rule call recorded and one per result such a call keeps, counted and never released (default 2000000). A parse that needs more is rejected with memoryBudget instead of growing.

reject_ambiguity: Option<bool>

Whether a reported ambiguity rejects the input (default false).

accept_recovery: Option<bool>

Whether a tree with ERROR or MISSING nodes is accepted (default false).

error_recovery: Option<bool>

Whether a failed parse is repaired into a tree with ERROR or MISSING nodes instead of rejected without a tree (default false).

max_repairs: Option<usize>

The bound on repair points of automatic recovery (default 32).

decorators: DecoratorSet

Decorators of the grammar-rule level, applied to the grammar a parser is compiled from, and of the executor and recovery levels, applied to every tree (see decorate_syntax_tree). An empty set keeps the decorators the parser was compiled with.
