Struct ParticleJsonWriter 

pub struct ParticleJsonWriter {
    pub include_bbox: bool,
    pub include_velocity: bool,
    pub include_properties: bool,
    pub precision: usize,
}

Writes particle data as compact JSON with optional bounding-box metadata.

Output schema:

{
  "time": 0.0,
  "step": 0,
  "bbox": { "min": [x,y,z], "max": [x,y,z] },
  "particles": [
    { "id": 0, "pos": [x,y,z], "vel": [vx,vy,vz], "mass": 1.0, "radius": 0.1 },
    ...
  ]
}

Fields

include_bbox: bool

Whether to include bounding-box metadata in the output.

include_velocity: bool

Whether to include the velocity array.

include_properties: bool

Whether to include named properties.

precision: usize

Decimal precision for floating-point numbers.

Implementations

impl ParticleJsonWriter

pub fn new() -> Self

Create a default writer (bbox on, velocity on, 6 decimal places).

pub fn write_to_string( ds: &ParticleDataset, include_bbox: bool, ) -> Result<String>

Write the dataset to a JSON string.

pub fn format(&self, ds: &ParticleDataset) -> Result<String>

Format the dataset according to this writer’s settings.

pub fn write_to_file(&self, ds: &ParticleDataset, path: &str) -> Result<()>

Write to a file.

Trait Implementations

impl Debug for ParticleJsonWriter

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

Formats the value using the given formatter.

impl Default for ParticleJsonWriter

fn default() -> ParticleJsonWriter

Returns the “default value” for a type.
