Enum LogLevel 

pub enum LogLevel {
    Off,
    Error,
    Warn,
    Info,
    Debug,
    Trace,
}

How much of the daemon’s own diagnostics reaches its log.

Written as one of the names below in [daemon] log_level or in SHEP_LOG_LEVEL, lowercase and nothing else, the same closed grammar log_json accepts, so a typo is a startup error naming the value rather than a level silently reverting to the default.

The default is LogLevel::Warn. The daemon’s records are dominated by warn-and-continue arms, each the only account of a decision the operator cannot otherwise see. LogLevel::Debug adds per-decision detail firing per dropped restart and per child metric sample, a firehose on a busy flock.

Variants

Off

Nothing at all: the daemon writes no records of its own.

Error

Only faults the daemon could not work around.

Warn

Faults the daemon worked around, and what working around them cost.

Info

Lifecycle milestones: the daemon came up, the daemon is going down.

Debug

Per-decision detail: every restart weighed, every metric sampled.

Trace

Everything the daemon can say about itself.

Implementations

impl LogLevel

pub const fn as_str(self) -> &'static str

The one spelling this level is written as, in the file and in the environment alike

pub fn from_name(name: &str) -> Option<Self>

The level name spells, or None when it spells no level.

The inverse of LogLevel::as_str, and exact: an uppercase or mixed-case name is not a level here, because SHEP_LOG_JSON accepts no TRUE either.
