Enum Severity 

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

REP-2012 severity levels, mirroring rcutils_log_severity_t.

The integer representation is stable and part of the ABI for nros_platform_log_write. Lower value = more verbose.

Variants

Trace = 0

Per-instruction granularity. Off unless max-level-trace is the active ceiling.

Debug = 1

Diagnostic information useful while developing.

Info = 2

Normal operation events worth surfacing once.

Warn = 3

Unexpected but recoverable conditions.

Error = 4

Errors the caller should surface; the system continues.

Fatal = 5

Unrecoverable — the system is about to abort.

Implementations

impl Severity

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

Short uppercase label suitable for log-line rendering.

pub const fn as_u8(self) -> u8

Stable u8 discriminant for cross-ABI use.

Trait Implementations

impl Clone for Severity

fn clone(&self) -> Severity

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Severity

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Severity

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Severity

fn cmp(&self, other: &Severity) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Severity

fn eq(&self, other: &Severity) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Severity

fn partial_cmp(&self, other: &Severity) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
