Struct AccountData 

pub struct AccountData {
    pub item_name: String,
    pub item_pos: usize,
    pub fields: AccountFields,
    pub changed_fields: AccountFields,
    pub is_snapshot: bool,
}

Representation of account data received from the IG Markets streaming API

Fields

item_name: String

Name of the item this data belongs to

item_pos: usize

Position of the item in the subscription

fields: AccountFields

All account fields

changed_fields: AccountFields

Fields that have changed in this update

is_snapshot: bool

Whether this is a snapshot or an update

Implementations

impl AccountData

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 an AccountData 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 application::streaming_convert (feature streaming).

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

• Result<Self, String> - The converted AccountData or an error message
