Struct TimelineSpan 

pub struct TimelineSpan {
    pub id: String,
    pub start: f64,
    pub end: f64,
    pub label: String,
    pub color: Color,
    pub lane: usize,
}

A span (duration) on the timeline.

Represents a range of time, rendered as a horizontal bar.

Example

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

let span = TimelineSpan::new("s1", 100.0, 500.0, "HTTP Request")
    .with_color(Color::Cyan)
    .with_lane(1);
assert_eq!(span.id, "s1");
assert_eq!(span.start, 100.0);
assert_eq!(span.end, 500.0);
assert_eq!(span.duration(), 400.0);
assert_eq!(span.lane, 1);

Fields

id: String

Unique identifier.

start: f64

Start timestamp.

end: f64

End timestamp.

label: String

Display label.

color: Color

Color for this span bar.

lane: usize

Optional row/lane index for vertical positioning.

Implementations

impl TimelineSpan

pub fn new( id: impl Into<String>, start: f64, end: f64, label: impl Into<String>, ) -> Self

Creates a new timeline span with default color and lane 0.

Example

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

let span = TimelineSpan::new("s1", 200.0, 800.0, "request-1");
assert_eq!(span.id, "s1");
assert_eq!(span.start, 200.0);
assert_eq!(span.end, 800.0);
assert_eq!(span.label, "request-1");
assert_eq!(span.color, Color::Cyan);
assert_eq!(span.lane, 0);

pub fn with_color(self, color: Color) -> Self

Sets the color (builder pattern).

Example

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

let span = TimelineSpan::new("s1", 0.0, 100.0, "task")
    .with_color(Color::Red);
assert_eq!(span.color, Color::Red);

pub fn set_color(&mut self, color: Color)

Sets the color.

Example

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

let mut span = TimelineSpan::new("s1", 0.0, 100.0, "task");
span.set_color(Color::Red);
assert_eq!(span.color, Color::Red);

pub fn color(&self) -> Color

Returns the color for this span bar.

Example

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

let span = TimelineSpan::new("s1", 0.0, 100.0, "task").with_color(Color::Red);
assert_eq!(span.color(), Color::Red);

pub fn with_lane(self, lane: usize) -> Self

Sets the lane (builder pattern).

Example

use envision::component::TimelineSpan;

let span = TimelineSpan::new("s1", 0.0, 100.0, "task")
    .with_lane(2);
assert_eq!(span.lane, 2);

pub fn duration(&self) -> f64

Returns the duration of this span.

Example

use envision::component::TimelineSpan;

let span = TimelineSpan::new("s1", 100.0, 400.0, "task");
assert_eq!(span.duration(), 300.0);

Trait Implementations

impl Clone for TimelineSpan

fn clone(&self) -> TimelineSpan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TimelineSpan

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TimelineSpan

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TimelineSpan

fn eq(&self, other: &TimelineSpan) -> 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 Serialize for TimelineSpan

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
