Struct RefillStatsData

pub struct RefillStatsData {
    pub duration_since_last_refill: u64,
    pub refill_volume_last_24h: f64,
    pub refill_count_last_24h: u64,
    pub refill_volume_last_hour: f64,
    pub refill_count_last_hour: u64,
}

Contains the data retrieved from the SQL database. It is also used to communicate data to be updated in the SQL database.

Fields

duration_since_last_refill: u64

Duration since the last refill operation in seconds

refill_volume_last_24h: f64

Total volume of refills in the last 24 hours in liters

refill_count_last_24h: u64

Count of refills in the last 24 hours

refill_volume_last_hour: f64

Total volume of refills in the last hour in liters

refill_count_last_hour: u64

Count of refills in the last hour

Implementations

impl RefillStatsData

pub fn new() -> RefillStatsData

Creates a new RefillStatsData instance, with all its fields initialized to zero.

This constructor provides a default, empty state for storing historical refill data, suitable for initialization before actual values are retrieved from the database.

Returns

A new RefillStatsData struct with all numeric fields set to 0 or 0.0.

Trait Implementations

impl Display for RefillStatsData

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

Provides a multi-line, human-readable output of the struct’s values for debugging purposes.

This implementation formats all fields of the RefillStatsData struct into a detailed string representation, summarizing historical refill statistics such as duration since the last refill, and total volume and count for both the last 24 hours and the last hour. This is particularly useful for inspecting refill data during development and logging.

Arguments

• f - A mutable reference to the formatter, as required by the fmt::Display trait.

Returns

An Ok(()) on successful formatting.

Errors

Returns an Err containing a std::fmt::Error if an I/O error occurs while writing to the formatter.
