Struct ParserLimits 

pub struct ParserLimits {
    pub max_depth: usize,
    pub max_input_bytes: usize,
    pub max_identifier_chars: usize,
}

Hard limits enforced by the parser.

The fields are public so the harness module (used by tests in tests/support/parser_hardening) can mutate them inline. Default values match production defaults.

Fields

max_depth: usize

Maximum recursion depth across recursive descent points (expressions, parenthesised sub-queries, JOIN chains).

max_input_bytes: usize

Maximum input length in bytes. Checked at the lexer entry before tokenization begins.

max_identifier_chars: usize

Maximum identifier length in characters. Checked when an identifier token is constructed in the lexer.

Implementations

impl ParserLimits

pub fn permissive() -> ParserLimits

Permissive limits for tests that intentionally probe deep nesting or long inputs without tripping DoS guards.

Trait Implementations

impl Clone for ParserLimits

fn clone(&self) -> ParserLimits

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ParserLimits

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for ParserLimits

fn default() -> ParserLimits

Returns the “default value” for a type.

impl PartialEq for ParserLimits

fn eq(&self, other: &ParserLimits) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
