Struct LossCurveDisplay 

pub struct LossCurveDisplay { /* private fields */ }

Wrapper for trueno-viz LossCurve with terminal output support.

Provides streaming loss curve visualization with:

• Train and validation loss tracking
• Exponential moving average smoothing
• Best value markers
• ASCII/Unicode/ANSI terminal rendering modes

Example

use entrenar::train::tui::LossCurveDisplay;

let mut display = LossCurveDisplay::new(80, 20);
display.push_train_loss(1.0);
display.push_val_loss(1.2);
println!("{}", display.render_terminal());

Implementations

impl LossCurveDisplay

pub fn new(width: u32, height: u32) -> Self

Create a new loss curve display.

pub fn terminal_mode(self, mode: TerminalMode) -> Self

Set terminal rendering mode.

pub fn smoothing(self, factor: f32) -> Self

Set smoothing factor (0.0 = none, 0.99 = heavy).

pub fn push_train_loss(&mut self, value: f32)

Push a training loss value.

pub fn push_val_loss(&mut self, value: f32)

Push a validation loss value.

pub fn push_losses(&mut self, train: f32, val: f32)

Push both train and val loss at once.

pub fn epochs(&self) -> usize

Get the number of epochs recorded.

pub fn summary(&self) -> Vec<SeriesSummaryTuple>

Get summary of all series.

pub fn render_terminal(&self) -> String

Render to terminal string.

pub fn print(&self)

Print to stdout.
