Public Member Functions | |
| template<typename T = void> | |
| SystemDefaultsQoS () | |
 Public Member Functions inherited from rclcpp::QoS | |
| constexpr bool | avoid_ros_namespace_conventions () const |
Whether to skip the /rt/ ROS topic-name prefix. | |
| constexpr QoS & | avoid_ros_namespace_conventions (bool on) |
| constexpr QoS & | best_effort () |
Set reliability to BEST_EFFORT (fire-and-forget; default for sensors). | |
| constexpr Duration | deadline () const |
The deadline window. Duration() (zero) = infinite. | |
| constexpr QoS & | deadline (const Duration &d) |
| constexpr int | depth () const |
Configured queue depth (only meaningful for KEEP_LAST). | |
| constexpr DurabilityPolicy | durability () const |
| The durability policy. | |
| constexpr QoS & | durability_volatile () |
Set durability to VOLATILE — late joiners get nothing (default). | |
| constexpr HistoryPolicy | history () const |
| The history policy. | |
| constexpr QoS & | keep_all () |
Use KEEP_ALL history (bounded by transport). | |
| constexpr QoS & | keep_last (int depth) |
| constexpr Duration | lifespan () const |
The lifespan window. Duration() (zero) = infinite. | |
| constexpr QoS & | lifespan (const Duration &d) |
| constexpr LivelinessPolicy | liveliness () const |
| The liveliness policy kind. | |
| constexpr QoS & | liveliness (LivelinessPolicy kind) |
| constexpr Duration | liveliness_lease_duration () const |
The liveliness lease window. Duration() (zero) = infinite. | |
| constexpr QoS & | liveliness_lease_duration (const Duration &d) |
| constexpr | QoS () |
| constexpr | QoS (::size_t depth) |
| constexpr ReliabilityPolicy | reliability () const |
| The reliability policy. | |
| constexpr QoS & | reliable () |
Set reliability to RELIABLE (acked transport, retransmits on loss). | |
| constexpr QoS & | transient_local () |
Set durability to TRANSIENT_LOCAL — late joiners get the last value. | |
| constexpr bool | tx_express () const |
| Whether this publisher's samples bypass transport tx batching. | |
| constexpr QoS & | tx_express (bool on) |

Detailed Description
rclcpp::SystemDefaultsQoS — REFUSE-LOUD.
Every field of rmw_qos_profile_system_default is a sentinel meaning "let
the RMW decide", and issue 0829 measured the two reference RMWs resolving the depth sentinel to different numbers (Cyclone 1, zenoh 42). rclcpp::QoS has no sentinel, deliberately — the backend is linked at build time, so there is nothing to defer to. Any concrete value here would be a different profile wearing this name, which is precisely what the old QoS(10) was.
