Struct Member 

#[non_exhaustive]
pub struct Member {
    pub change: f64,
    pub volume: f64,
    pub new_high: bool,
    pub new_low: bool,
    pub above_ma: bool,
    pub on_buy_signal: bool,
}

One symbol’s contribution to a CrossSection tick.

Field invariants enforced by CrossSection::new when the member is placed into a tick:

• change is finite (its sign classifies the symbol — positive is advancing, negative is declining, zero is unchanged).
• volume is finite and non-negative.

new_high / new_low are caller-supplied flags marking whether the symbol printed a new period extreme; above_ma / on_buy_signal are caller-supplied per-symbol state signals (whether the symbol trades above its reference moving average, and whether it is on a point-and-figure buy signal). None of the four flags carries a numeric invariant.

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.

change: f64

Price change versus the previous close. Sign classifies the symbol: positive is advancing, negative is declining, zero is unchanged.

volume: f64

Period volume for the symbol (finite, non-negative).

new_high: bool

Whether the symbol printed a new period high.

new_low: bool

Whether the symbol printed a new period low.

above_ma: bool

Whether the symbol is trading above its reference moving average (consumed by the % Above Moving Average breadth indicator).

on_buy_signal: bool

Whether the symbol is on a point-and-figure buy signal (consumed by the Bullish Percent Index breadth indicator).

Implementations

impl Member

pub const fn new( change: f64, volume: f64, new_high: bool, new_low: bool, ) -> Self

Assemble a cross-section member from its core signals, leaving the extended per-symbol state flags (above_ma, on_buy_signal) cleared.

The field invariants documented on Member are validated centrally by CrossSection::new when the member is placed into a tick; this constructor only assembles the value so the #[non_exhaustive] struct can be built from outside the crate.

pub const fn with_signals( change: f64, volume: f64, new_high: bool, new_low: bool, above_ma: bool, on_buy_signal: bool, ) -> Self

Assemble a cross-section member including the extended per-symbol state signals above_ma and on_buy_signal.

Use this constructor for the breadth indicators that read per-symbol state (% Above Moving Average, Bullish Percent Index); new is the shorthand that leaves both flags false.

Trait Implementations

impl Clone for Member

fn clone(&self) -> Member

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Member

impl Debug for Member

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Member

fn eq(&self, other: &Member) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
