Struct ComplexityGuardOptions 

pub struct ComplexityGuardOptions {
    pub max_input_bytes: Option<usize>,
    pub max_tokens: Option<usize>,
    pub max_ast_nodes: Option<usize>,
    pub max_ast_depth: Option<usize>,
    pub max_parenthesis_depth: Option<usize>,
    pub max_function_call_depth: Option<usize>,
}

Guard options for parse/transpile/generate complexity.

These limits turn excessively deep or large inputs into regular errors instead of relying on process stack exhaustion as the failure mode.

Fields

max_input_bytes: Option<usize>

Maximum allowed SQL input size in bytes. None disables this check.

max_tokens: Option<usize>

Maximum allowed number of tokens after tokenization. None disables this check.

max_ast_nodes: Option<usize>

Maximum allowed AST node count after parsing. None disables this check.

max_ast_depth: Option<usize>

Maximum allowed AST depth after parsing. None disables this check.

max_parenthesis_depth: Option<usize>

Maximum allowed nested parenthesis depth before parsing. None disables this check.

max_function_call_depth: Option<usize>

Maximum allowed nested function-call depth before parsing. None disables this check.

Trait Implementations

impl Clone for ComplexityGuardOptions

fn clone(&self) -> ComplexityGuardOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ComplexityGuardOptions

impl Debug for ComplexityGuardOptions

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

Formats the value using the given formatter.

impl Default for ComplexityGuardOptions

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ComplexityGuardOptions

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ComplexityGuardOptions

impl PartialEq for ComplexityGuardOptions

fn eq(&self, other: &ComplexityGuardOptions) -> 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.

impl Serialize for ComplexityGuardOptions

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
