extern struct Hello [src]

WebSocket server->client. Sent by the server as the first message after a WebSocket connection opens to provide basic information about the server, the build graph, etc. Trailing: step_name_len: u32 for each steps_len step_name: [step_name_len]u8 for each step_name_len step_status: u8 for every 4 steps_len; every 2 bits is a StepUpdate.Status, LSBs first

Fields

tag: ToClientTag = .hello

status: BuildStatus

flags: Flags

timestamp: i64 align(4)Any message containing a timestamp represents it as a number of nanoseconds relative to when the build began. This field is the current timestamp, represented in that form.

steps_len: u32 align(1)The number of steps in the build graph which are reachable from the top-level step[s] being run; in other words, the number of steps which will be executed by this build. The name of each step trails this message.
