Detailed Description

One drained runtime event.

Events have a fixed stride and hold no pointers, so a host can copy a whole batch with one memory copy.

Step through an array of these by mln_runtime_event_batch.event_size rather than by the size of this struct: a later version may add a member to mln_runtime_event_payload and widen the stride. Every field below, payload included, keeps its offset across versions.

Field Documentation

◆ code

int32_t mln_runtime_event::code

Secondary event detail whose meaning type selects. Depending on type it carries an mln_camera_change_mode, an mln_status, a MapLibre Native error ordinal, or 0. See mln_runtime_event_type for the per-type meaning.

◆ message_offset

uint32_t mln_runtime_event::message_offset

Byte offset of this event's message inside mln_runtime_event_batch.messages. Zero when message_size is 0.

◆ message_size

uint32_t mln_runtime_event::message_size

Number of message bytes, excluding the trailing null terminator that follows them in the arena. Zero when this event carries no message.

◆ payload

mln_runtime_event_payload mln_runtime_event::payload

Typed payload selected by payload_type.

◆ payload_type

uint32_t mln_runtime_event::payload_type

One of mln_runtime_event_payload_type.

◆ source

uint64_t mln_runtime_event::source

Source handle for this event: the mln_map for map-originated events, the mln_runtime for runtime-originated events, selected by source_type. Every handle type is uint64_t, so this needs no cast.

The value names one object for the life of the process, so a host may compare it against a handle it holds even after that handle is released.

◆ source_type

uint32_t mln_runtime_event::source_type

One of mln_runtime_event_source_type.

◆ type

uint32_t mln_runtime_event::type

One of mln_runtime_event_type.
