Struct ProtocolLimits 

pub struct ProtocolLimits {
    pub max_packet_bytes: usize,
    pub max_frame_bytes: usize,
    pub max_response_bytes: usize,
    pub max_columns: usize,
    pub max_binds: usize,
    pub max_batch_rows: usize,

    pub max_lob_chunks: usize,
    pub max_length_prefixed_elements: usize,
}

Central resource policy for thin protocol decoding.

The values are deliberately collected in one copyable struct so connection, packet, TTC, object, vector, LOB, and notification decoders all share the same vocabulary for resource bounds. W1-T5.2 threads this policy through the current decoder call graph; this type is the single source of those limits.

Fields

max_packet_bytes: usize

Maximum encoded TNS packet size.

max_frame_bytes: usize

Maximum decoded logical TTC frame/message size.

max_response_bytes: usize

Maximum cumulative bytes accepted for one server response.

max_columns: usize

Maximum number of columns in one describe/fetch shape.

max_binds: usize

Maximum bind count in one execute/batch request.

max_batch_rows: usize

Maximum row count in one client-side batch operation.

max_object_depth: usize

Maximum recursive object/JSON nesting depth.

max_object_elements: usize

Maximum element/member count in one decoded object/JSON container.

max_vector_dimensions: usize

Maximum VECTOR dimensions.

max_lob_chunks: usize

Maximum number of LOB chunks in one logical LOB operation.

max_length_prefixed_elements: usize

Maximum elements in generic length-prefixed wire collections.

Trait Implementations

impl Clone for ProtocolLimits

fn clone(&self) -> ProtocolLimits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ProtocolLimits

impl Debug for ProtocolLimits

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

Formats the value using the given formatter.

impl Default for ProtocolLimits

fn default() -> Self

Returns the “default value” for a type.

impl Eq for ProtocolLimits

impl PartialEq for ProtocolLimits

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