Struct CRWriter

pub struct CRWriter {
    pub file: File,
    pub file_path: String,
    pub pkts_per_file: usize,
    pub mbytes_per_file: usize,
    pub file_name: String,
    pub run_id: u32,
    pub file_timestamp: Option<String>,
    /* private fields */
}

Write CRFrames to disk.

Operates sequentially, frames can be added one at a time, then will be synced to disk.

Fields

file: File

file_path: String

location to store the file

pkts_per_file: usize

The maximum number of packets for a single file. Ater this number is reached, a new file is started.

mbytes_per_file: usize

The maximum number of (Mega)bytes per file. After this a new file is started

file_name: String

run_id: u32

file_timestamp: Option<String>

it can also take a timestamp, in case we don’t want to use the current time when the file is written

Implementations

impl CRWriter

pub fn new( file_path: String, run_id: u32, subrun_id: Option<u64>, timestamp: Option<String>, ) -> Self

Instantiate a new PacketWriter

Arguments

• file_path : Path to store the file under
• run_id : Run ID for this file (will be written in filename)
• subrun_id : Sub-Run ID for this file (will be written in filename. If None, a generic “0” will be used
• timestamp : The writer will add an automatic timestamp to the current file based on the current time. This option allows to overwrite that behaviour

pub fn get_file(&self, timestamp: Option<String>) -> File

pub fn add_frame(&mut self, frame: &CRFrame)

Induce serialization to disk for a CRFrame

Trait Implementations

impl Default for CRWriter

fn default() -> Self

Returns the “default value” for a type.

impl Display for CRWriter

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

Formats the value using the given formatter.
