Struct PriceData 

pub struct PriceData {
    pub item_name: String,
    pub item_pos: usize,
    pub fields: PriceFields,
    pub changed_fields: PriceFields,
    pub is_snapshot: bool,
}

Structure for price data received from the IG Markets API Contains information about market prices and related data

Fields

item_name: String

Name of the item (usually the market ID)

item_pos: usize

Position of the item in the subscription

fields: PriceFields

All price fields for this market

changed_fields: PriceFields

Fields that have changed in this update

is_snapshot: bool

Whether this is a snapshot or an update

Implementations

impl PriceData

pub fn from_fields( item_name: Option<&str>, item_pos: usize, is_snapshot: bool, fields: &HashMap<String, Option<String>>, changed_fields: &HashMap<String, Option<String>>, ) -> Result<Self, String>

Builds a PriceData from pre-extracted streaming fields.

This is transport-agnostic: it takes plain field maps rather than a Lightstreamer ItemUpdate, so the presentation layer carries no dependency on the streaming transport. The ItemUpdate adapter lives in crate::application::streaming_convert.

Arguments

• item_name - Subscription item name (None when subscribed by position)
• item_pos - 1-based position of the item in the subscription
• is_snapshot - Whether this update is a snapshot
• fields - Current field values for the item
• changed_fields - Field values that changed in this update

Returns

A Result containing either the parsed PriceData or an error message
