Struct MarketSnapshot 

#[non_exhaustive]
pub struct MarketSnapshot {

    pub symbol: Option<String>,
    pub name: Option<String>,
    pub asset_class: Option<AssetClass>,
    pub market_status: Option<String>,
    pub last_price: Option<f64>,
    pub bid: Option<f64>,
    pub ask: Option<f64>,
    pub open: Option<f64>,
    pub high: Option<f64>,
    pub low: Option<f64>,
    pub close: Option<f64>,
    pub previous_close: Option<f64>,
    pub volume: Option<f64>,
    pub change: Option<f64>,
    pub change_percent: Option<f64>,
    pub error: Option<String>,
    pub message: Option<String>,
}

One symbol’s current market state, flattened across asset classes.

Providers return a row per requested symbol even when the lookup failed, so a batch is never silently short: check error before reading the price fields.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

symbol: Option<String>

Ticker symbol as the provider spells it (e.g. "AAPL", "X:BTCUSD").

name: Option<String>

Human-readable name of the instrument.

asset_class: Option<AssetClass>

Market this row belongs to.

market_status: Option<String>

Trading status of that market (e.g. "open", "closed").

last_price: Option<f64>

Most recent trade price.

bid: Option<f64>

Best bid.

ask: Option<f64>

Best ask.

open: Option<f64>

Session open.

high: Option<f64>

Session high.

low: Option<f64>

Session low.

close: Option<f64>

Session close (last price of the current session).

previous_close: Option<f64>

Previous session’s close.

volume: Option<f64>

Session volume.

change: Option<f64>

Absolute change over the session.

change_percent: Option<f64>

Percentage change over the session.

error: Option<String>

Per-symbol error code, if the provider could not resolve this symbol.

message: Option<String>

Human-readable message accompanying error.
