Struct TickFilter 

pub struct TickFilter { /* private fields */ }

Filters ticks by optional symbol, side, price range, and minimum quantity predicates.

All predicates are ANDed together. Unset predicates always pass.

Implementations

impl TickFilter

pub fn new() -> Self

Creates a new TickFilter with no predicates set (matches everything).

pub fn symbol(self, s: Symbol) -> Self

Restrict matches to ticks with this symbol.

pub fn side(self, s: Side) -> Self

Restrict matches to ticks on this side.

pub fn min_quantity(self, q: Quantity) -> Self

Restrict matches to ticks with quantity >= q.

pub fn max_quantity(self, q: Quantity) -> Self

Restrict matches to ticks with quantity <= q.

pub fn min_price(self, p: Price) -> Self

Restrict matches to ticks with price >= p.

pub fn max_price(self, p: Price) -> Self

Restrict matches to ticks with price <= p.

pub fn min_notional(self, n: Decimal) -> Self

Restrict matches to ticks with notional (price * quantity) >= n.

pub fn max_notional(self, n: Decimal) -> Self

Restrict matches to ticks with notional (price * quantity) <= n.

pub fn timestamp_range(self, from: NanoTimestamp, to: NanoTimestamp) -> Self

Restrict matches to ticks whose timestamp falls within [from, to] (inclusive).

pub fn has_symbol_filter(&self) -> bool

Returns true if a symbol predicate has been set on this filter.

pub fn has_side_filter(&self) -> bool

Returns true if a side predicate has been set on this filter.

pub fn has_min_qty_filter(&self) -> bool

Returns true if a minimum quantity predicate has been set on this filter.

pub fn has_price_filter(&self) -> bool

Returns true if a price range predicate has been set on this filter.

pub fn has_notional_filter(&self) -> bool

Returns true if a notional (min or max) predicate has been set on this filter.

pub fn clear(self) -> Self

Resets all predicates, returning a fresh filter that matches every tick.

Allows reuse of a filter builder without allocating a new one.

pub fn is_empty(&self) -> bool

Returns true if no predicates are configured — the filter matches any tick.

Callers can skip filter evaluation entirely when no constraints have been set, avoiding unnecessary field comparisons on every tick.

pub fn matches(&self, tick: &Tick) -> bool

Returns true if the tick satisfies all configured predicates.

pub fn count_matches(&self, ticks: &[Tick]) -> usize

Returns the number of ticks in ticks that satisfy all predicates.

Equivalent to ticks.iter().filter(|t| self.matches(t)).count() but avoids allocating a filtered collection.

Trait Implementations

impl Clone for TickFilter

fn clone(&self) -> TickFilter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for TickFilter

fn default() -> Self

Returns the “default value” for a type.
