The commands service, reached through its host.

Provided Methods

fn refresh_commands(&mut self)

Side: server. A mod changed the commands it registers (native_register_commands): at the start of the next server tick every mod is asked again, the commands players may run are rebuilt, and every player on the server is sent their tree again, after native_player_commands_sent. Nothing happens where no world is open to players, and nothing for a server whose mods never call it. API @API:refresh_commands@.

fn feedback(&mut self, line: Text) -> Result<(), TextFormError>

Side: server. A command’s success feedback, routed to its originating source using vanilla’s silence, send-command-feedback and block/cart track-output rules. Refuses text deeper than 512 component nodes before applying any changes.

fn run_command(&mut self, line: &str) -> bool

Side: server. Runs line (no slash) as the server’s console does: permission level 4, from the overworld’s spawn, with no output. A teleport to another level (execute in minecraft:the_nether run tp Alex 0 70 0) happens at the next tick’s start, as the console’s. Whether it ran without failing. During a guest’s turn, live players (including the acting player) are reachable; displaced outer players are excluded from name, UUID and selector resolution on this path only.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
