Enum TraceLevel 

#[repr(u8)]
pub enum TraceLevel {
    Off = 0,
    Error = 1,
    Warn = 2,
    Info = 3,
    Debug = 4,
    Trace = 5,
}

Trace verbosity. Ordered least→most verbose; a record at record.level is kept iff record.level <= gate. Records always carry Error..=Trace; Off is a gate-only value (a gate of Off keeps nothing).

#[repr(u8)] with explicit discriminants so the value round-trips through the hot-path HotGate atomic (as_u8 / from_u8) without changing the derived Ord (declaration order == numeric order).

Variants

Off = 0

Gate-only: silence this plugin entirely.

Error = 1

Warn = 2

Info = 3

Debug = 4

Trace = 5

Implementations

impl TraceLevel

pub const ALL: [TraceLevel; 6]

The six levels least→most verbose — the canonical order for enumeration (:set completion, the customize view) and cycling.

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

The lowercase wire / display label (off / error / … / trace).

pub fn cycle_next(self) -> TraceLevel

The next level in ALL order, wrapping Trace → Off — the manager view’s per-plugin cycle chord (PO.4.3).

pub fn parse(s: &str) -> Option<TraceLevel>

Parse a lowercase label (inverse of as_str), None for an unknown word. The loader uses this to bridge a plugin.trace-level OptionChanged (whose value arrives as a string) into a level (PO.4.3).

pub fn as_u8(self) -> u8

The numeric encoding stored in the HotGate atomic.

pub fn from_u8(v: u8) -> Self

Decode a HotGate atomic byte. An out-of-range byte (never written by this crate) decodes to Off — observability fails closed, never panics.
