Struct FormatGuardOptions 

pub struct FormatGuardOptions {
    pub max_input_bytes: Option<usize>,
    pub max_tokens: Option<usize>,
    pub max_ast_nodes: Option<usize>,
    pub max_set_op_chain: Option<usize>,
}

Guard options for SQL pretty-formatting.

These limits protect against extremely large/complex queries that can cause high memory pressure in constrained runtimes (for example browser WASM).

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_set_op_chain: Option<usize>

Maximum allowed count of set-operation operators (UNION/INTERSECT/EXCEPT) observed in a statement before parsing.

None disables this check.
