fastc-core-log

Structured leveled logging for fastC.

Part of the fastc-core launch set. The implementation ships in the fastC v1.0 prelude — every use log::* works out of the box.

Surface

use log::debug;
use log::info;
use log::warn;
use log::error;
use log::kv_int;
use log::kv_str;

// Threshold levels:
use log::level_debug;   // 0
use log::level_info;    // 1
use log::level_warn;    // 2
use log::level_error;   // 3

Example

use log::info;
use log::warn;
use log::kv_int;
use log::kv_str;

fn main() -> i32 {
    info(cstr("starting up"));
    kv_str(cstr("user"), cstr("alice"));
    kv_int(cstr("requests"), 42);
    info(cstr("hourly stats"));
    warn(cstr("disk usage high"));
    return 0;
}

Outputs:

[INFO] starting up
user="alice" requests=42 [INFO] hourly stats
[WARN] disk usage high

kv_* helpers emit on the same line without a terminator and pair with a closing info / warn / error call. All log functions allocate nothing — safe inside @noalloc blocks.

Status

v0.1.0 — preview. API is final; will become installable via fastc add once consumption ships.
