Trait StatRec

pub trait StatRec: HasRType {
    const UNDEF_STAT_QUANTITY: i64;

    // Required methods
    fn stat_type(&self) -> Result<StatType>;
    fn ts_recv(&self) -> Option<OffsetDateTime>;
    fn ts_ref(&self) -> Option<OffsetDateTime>;
    fn update_action(&self) -> Result<StatUpdateAction>;
    fn price(&self) -> i64;
    fn quantity(&self) -> i64;
}

A trait for compatibility between different versions of statistics records.

Required Associated Constants

const UNDEF_STAT_QUANTITY: i64

The sentinel value for a null quantity.

Required Methods

fn stat_type(&self) -> Result<StatType>

Tries to convert the raw type of the statistic value to an enum.

Errors

This function returns an error if the stat_type field does not contain a valid StatType.

fn ts_recv(&self) -> Option<OffsetDateTime>

Parses the raw capture-server-received timestamp into a datetime. Returns None if ts_recv contains the sentinel for a null timestamp.

fn ts_ref(&self) -> Option<OffsetDateTime>

Parses the raw reference timestamp of the statistic value into a datetime. Returns None if ts_ref contains the sentinel for a null timestamp.

fn update_action(&self) -> Result<StatUpdateAction>

Tries to convert the raw update_action to an enum.

Errors

This function returns an error if the update_action field does not contain a valid StatUpdateAction.

fn price(&self) -> i64

The value for price statistics expressed as a signed integer where every 1 unit corresponds to 1e-9, i.e. 1/1,000,000,000 or 0.000000001. Will be UNDEF_PRICE when unused.

fn quantity(&self) -> i64

The value for quantity statistics. Will be UNDEF_STAT_QUANTITY when unused.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
