Enum EventLevel 

pub enum EventLevel {
    Trace,
    Debug,
    Info,
    Warning,
    Error,
    Fatal,
}

Severity level for a stream event.

Levels are ordered from least to most severe, allowing minimum-level filtering (e.g., show only Warning and above).

Example

use envision::component::EventLevel;

assert!(EventLevel::Error > EventLevel::Info);
assert!(EventLevel::Trace < EventLevel::Debug);
assert_eq!(EventLevel::default(), EventLevel::Info);

Variants

Trace

Finest-grained informational events.

Debug

Fine-grained informational events useful for debugging.

Info

Informational messages highlighting normal operation.

Warning

Potentially harmful situations.

Error

Error events that might still allow the application to continue.

Fatal

Very severe error events that will likely cause the application to abort.

Implementations

impl EventLevel

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

Returns a short abbreviation for display (3 chars).

Example

use envision::component::EventLevel;

assert_eq!(EventLevel::Info.abbreviation(), "INF");
assert_eq!(EventLevel::Error.abbreviation(), "ERR");

pub fn color(&self) -> Color

Returns the display color for this severity level.

• Trace: DarkGray (dim)
• Debug: Gray
• Info: Blue
• Warning: Yellow
• Error: Red
• Fatal: LightRed (bright red)

Example

use envision::component::EventLevel;
use ratatui::style::Color;

assert_eq!(EventLevel::Info.color(), Color::Blue);
assert_eq!(EventLevel::Error.color(), Color::Red);

Trait Implementations

impl Clone for EventLevel

fn clone(&self) -> EventLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EventLevel

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

Formats the value using the given formatter.

impl Default for EventLevel

fn default() -> EventLevel

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for EventLevel

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for EventLevel

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

Formats the value using the given formatter.

impl Hash for EventLevel

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 EventLevel

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

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

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

impl Serialize for EventLevel

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
