Struct UserFill 

pub struct UserFill {
    pub coin: String,
    pub side: String,
    pub px: String,
    pub sz: String,
    pub time: u64,
    pub oid: u64,
    pub fee: String,
    pub tid: u64,
    pub fee_token: Option<String>,
    pub cloid: Option<String>,
}

Parse a decimal string from SDK response, logging warnings on failure. One fill from the userFills info endpoint, as the venue actually returns it.

Why this exists rather than hyperliquid_rust_sdk::UserFillsResponse

The SDK’s type does not model tid, the only per-fill identifier the endpoint offers, and it does not model feeToken. Neither omission is visible at runtime: the SDK does not set deny_unknown_fields, so both are parsed away silently. Without tid the only id left is hash, which identifies the transaction — one aggressive order sweeping several resting orders produces several fills under a single hash, and they are then indistinguishable.

Only the fields this client reads are declared. Unknown fields are ignored, so hash, closedPnl, dir, startPosition, crossed and builderFee cost nothing by being absent here.

Drop this in favour of the SDK type if it ever models tid.

Fields

coin: String

side: String

px: String

sz: String

time: u64

oid: u64

fee: String

tid: u64

Identifies this fill. hash identifies the transaction that contained it, and one transaction can contain many fills.

Declared required rather than Option<u64> deliberately. If the venue ever stops sending it, this client should fail loudly at the parse — falling back to hash would silently restore a duplicate-id defect that is invisible until fills go missing during reconciliation.

Hyperliquid documents this as unique per fill, but qualified by coin rather than global, which is why the dedup cache keys on the instrument alongside it.

fee_token: Option<String>

Asset the fee is denominated in.

Optional because, unlike every other field here, nothing proves the endpoint sends it: the SDK’s own type omits it, so it has never been observed through this dependency. The caller falls back to inferring the asset from the side when it is absent.

cloid: Option<String>

The cloid of the order filled, in the venue’s form (cloid_to_cid). Absent for an order placed without one.
