Struct Target 

pub struct Target {
    pub kind: TargetKind,
    pub id: String,
    pub chain: Option<String>,
    pub venues: Vec<String>,
    pub preset: Option<Preset>,
    pub health: HealthOverrides,
    pub rules: Vec<Rule>,
}

One thing a watchlist watches.

Fields

kind: TargetKind

id: String

A symbol, a contract address or a wallet address.

chain: Option<String>

The chain; inferred when absent, as the CLI does.

venues: Vec<String>

The venues, for market metrics, in the user’s order. Empty: none.

preset: Option<Preset>

A preset, evaluated before the rules.

health: HealthOverrides

Health threshold overrides for the preset and the market metrics.

rules: Vec<Rule>

Implementations

impl Target

pub fn new(kind: TargetKind, id: impl Into<String>) -> Self

A target with no venue, preset or rules.

pub fn label(&self) -> String

The name of the whole target: USDC@binance, USDC@binance,okx, or the id.

pub fn row_label(&self, venue: Option<&str>) -> String

The label of one row of the target: USDC@binance on a venue, the id without one.

pub fn rows(&self) -> Vec<Option<&str>>

The rows the target gives, by venue (None: the id row). One venue or none: one row with every cell. Two or more: one market row per venue, then an id row when token or address rules need one (design 2026-11-04, section 2.3). With no market metric, the venues read nothing, so the target is its id row alone.

pub fn needs_market(&self) -> bool

Whether the target reads a market summary (preset or a market rule).

pub fn needs(&self, group: MetricGroup) -> bool

Whether any rule reads a metric of group.
