Struct CheckpointHeader 

pub struct CheckpointHeader {
    pub step: u64,
    pub time: f64,
    pub n_ranks: usize,
    pub n_items: usize,
    pub tag: String,
}

Header record written at the start of every checkpoint file.

Fields

step: u64

Simulation step index.

time: f64

Simulation time.

n_ranks: usize

Number of MPI ranks used when the checkpoint was written.

n_items: usize

Number of particles/cells in this checkpoint.

tag: String

A user-defined tag (simulation name, version, etc.).

Implementations

Create a new checkpoint header.

pub fn to_line(&self) -> String

Serialize to a single-line text format.

pub fn from_line(line: &str) -> Option<Self>

Parse a checkpoint header from a text line.
