Enum VolumeSource 

pub enum VolumeSource {
    TradeSize,
    TickCount,
    ExchangeReported,
    Unknown,
}

Origin of the candle volume figure.

Tracks whether volume represents actual trade quantities, tick count fallback, exchange-reported aggregates, or unknown legacy data.

Variants

TradeSize

Sum of individual trade sizes from exchange (crypto spot/perps).

TickCount

Number of quote changes — fallback when no real volume (FX, some CFDs).

ExchangeReported

Official aggregate volume from a data provider API (EODHD, CCData).

Unknown

Volume origin unknown or not determinable (legacy, CSV imports).

Implementations

impl VolumeSource

pub fn as_str(&self) -> &str

String representation for database storage.

pub fn from_str_value(s: &str) -> Self

Parse from database string representation.

Trait Implementations

impl Clone for VolumeSource

fn clone(&self) -> VolumeSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VolumeSource

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

Formats the value using the given formatter.

impl Default for VolumeSource

fn default() -> VolumeSource

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for VolumeSource

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for VolumeSource

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

Formats the value using the given formatter.

impl PartialEq for VolumeSource

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for VolumeSource

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
