    pub is_realtime: Option<bool>,
    pub is_end_of_history: Option<bool>,
    pub epoch: Option<u64>,
    pub bar_status: Option<String>,
}

OHLCV bar from the barcharts endpoint.

All numeric fields are returned as strings by the API. Use Bar::ohlcv to parse them into native types.

Example

if let Some((o, h, l, c, v)) = bar.ohlcv() {
    println!("close={c}, volume={v}");
}

Fields

high: String

Highest price during the bar period.

low: String

Lowest price during the bar period.

open: String

Opening price.

close: String

Closing price.

time_stamp: String

Bar timestamp (RFC 3339).

total_volume: String

Total volume traded during the bar period.

down_ticks: Option<Value>

Number of down ticks.

down_volume: Option<Value>

Volume on down ticks.

open_interest: Option<Value>

Open interest (futures/options).

total_ticks: Option<Value>

Total number of ticks.

unchanged_ticks: Option<Value>

Number of unchanged ticks.

unchanged_volume: Option<Value>

Volume on unchanged ticks.

up_ticks: Option<Value>

Number of up ticks.

up_volume: Option<Value>

Volume on up ticks.

is_realtime: Option<bool>

Whether this bar is from real-time data.

is_end_of_history: Option<bool>

Whether this is the last bar in the history.

epoch: Option<u64>

Unix epoch timestamp in milliseconds.

bar_status: Option<String>

Bar status (e.g., “Closed”, “Open”).

Implementations

impl Bar

pub fn ohlcv(&self) -> Option<(f64, f64, f64, f64, u64)>

Parse OHLCV string fields into (open, high, low, close, volume).

Returns None if any field fails to parse.

pub fn timestamp(&self) -> Option<DateTime<Utc>>

Parse the bar timestamp into a DateTime<Utc>.

Returns None if the timestamp is not valid RFC 3339.

Trait Implementations

impl Clone for Bar

fn clone(&self) -> Bar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Bar

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Bar

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Bar

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
