Struct firefly_types::Stats

pub struct Stats {
    pub minutes: [u32; 4],
    pub longest_play: [u32; 4],
    pub launches: [u32; 4],
    pub installed_on: (u16, u8, u8),
    pub launched_on: (u16, u8, u8),
}

Player-specific app stats, like playtime.

Fields

minutes: [u32; 4]

How many minutes the app was played for every player count from 1 to 4+.

Games with more than 4 players are recorded as 4 players. So, the last index (3) is “4+ players”.

The play time is calculated based on the number of the calls to the update callback. So, the number is an approximation and may drift a bit.

Plays shorter than 1 minute are not recorded.

longest_play: [u32; 4]

How many minutes the app was played the longest for every player count from 1 to 4+.

Use this metric carefully. The runtime might or might not account for players pausing the app for days instead of exiting it. Which means, multiple play sessions may be counted as one.

launches: [u32; 4]

How many times the app was launched for every player count from 1 to 4+.

installed_on: (u16, u8, u8)

The date when the app was installed.

The date is a tuple of year, month, and day of month.

launched_on: (u16, u8, u8)

The date when the app was launched last time.

The date is a tuple of year, month, and day of month.

Implementations

impl Stats

pub fn decode(s: &[u8]) -> Result<Self, Error>

Load stats from bytes generated by Stats::encode.

Errors

May return an error if the buffer does not contain valid stats.

pub fn encode<'b>(&self, buf: &'b mut [u8]) -> Result<&'b mut [u8], Error>

Encode the stats using the buffer.

The buffer is required to avoid allocations on the crate side. Use Stats::size to calculate the required buffer size.

Errors

May return an error if the buffer is not big enough.

pub fn size(&self) -> usize

Calculate the buffer size required to encode the stats.

Trait Implementations

impl Clone for Stats

fn clone(&self) -> Stats

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Stats

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Stats

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Stats

fn eq(&self, other: &Stats) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Stats

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
