Struct BufferWatermarks 

pub struct BufferWatermarks {
    pub low: usize,
    pub high: usize,
}

Two-tier buffer watermarks for back-pressure control.

Example

use trueno::brick::BufferWatermarks;

let wm = BufferWatermarks::default();
assert!(!wm.should_backpressure(1000));  // Below high watermark
assert!(wm.should_backpressure(10000));  // Above high watermark

Fields

low: usize

Low watermark: resume writing when buffer drops below this

high: usize

High watermark: apply back-pressure when buffer exceeds this

Implementations

impl BufferWatermarks

pub fn new(low: usize, high: usize) -> Self

Create new watermarks.

Panics

Panics if low >= high.

pub fn should_backpressure(&self, current: usize) -> bool

Check if back-pressure should be applied.

pub fn can_write(&self, current: usize) -> bool

Check if writing can resume.

pub fn pressure_level(&self, current: usize) -> f64

Get pressure level (0.0 = empty, 1.0 = at high watermark).
