Struct ParserConfig 

pub struct ParserConfig {
    pub max_depth: usize,
    pub unicode_ops: bool,
    pub suggestions: bool,
    pub error_recovery: bool,
    pub allow_commands: bool,
}

Configuration options for the parser.

These influence how the parser handles ambiguity, error recovery, and diagnostic reporting.

Fields

max_depth: usize

Maximum expression nesting depth before the parser gives up.

Default: 512.

unicode_ops: bool

Whether to enable experimental Unicode operator support.

Default: true.

suggestions: bool

Whether to emit “did you mean?” suggestions on parse errors.

Default: true.

error_recovery: bool

Whether to allow recovery from parse errors and continue parsing.

Default: false (strict mode).

allow_commands: bool

Whether #check, #eval, and similar commands are permitted.

Default: true.
