Enum Level 

pub enum Level {
    Trace = 10,
    Debug = 20,
    Info = 30,
    Warn = 40,
    Error = 50,
    Fatal = 60,
}

Canonical log level enumeration.

Ordered by severity (ascending) for >= filtering via Ord. Each variant has a numeric discriminant matching the bunyan/pino convention:

• Trace = 10
• Debug = 20
• Info = 30
• Warn = 40
• Error = 50
• Fatal = 60

Variants

Trace = 10

Debug = 20

Info = 30

Warn = 40

Error = 50

Fatal = 60

Implementations

impl Level

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

5-character display badge for the level, right-justified (e.g., " INFO", "ERROR").

pub const fn blank_badge() -> &'static str

The blank badge (5 spaces) used when no level is recognized.

pub const fn style(&self) -> Style

Returns the Style for this level’s badge when colors are enabled.

Color scheme follows fblog convention:

• Trace: cyan bold
• Debug: blue bold
• Info: green bold
• Warn: yellow bold
• Error: red bold
• Fatal: magenta bold

pub fn style_with_color(&self, custom_color: Option<&str>) -> Style

Returns the Style for this level’s badge, using a custom color if provided.

If custom_color is None, falls back to the default color scheme.

pub fn from_str_loose(s: &str) -> Option<Self>

Parse a string into a Level, case-insensitive.

Returns None for unrecognized strings.

pub const fn from_numeric(n: i64) -> Self

Parse a numeric value into a Level using nearest-match rounding.

Uses bunyan/pino numeric convention:

• 10 = trace, 20 = debug, 30 = info, 40 = warn, 50 = error, 60 = fatal

Values between thresholds round to the nearest lower level.

pub fn from_json_value( value: &Value, custom_aliases: Option<&HashMap<String, Self>>, ) -> Option<Self>

Parse a level from a serde_json::Value.

Handles both string and numeric representations.

Trait Implementations

impl Clone for Level

fn clone(&self) -> Level

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Level

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

Formats the value using the given formatter.

impl Display for Level

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

Formats the value using the given formatter.

impl Hash for Level

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 Level

fn cmp(&self, other: &Level) -> 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 Level

fn eq(&self, other: &Level) -> 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 Level

fn partial_cmp(&self, other: &Level) -> 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.
