A boolean node — evaluates to true/false each bar.

Variants

Gt((Operand, Operand))

a > b.

Lt((Operand, Operand))

a < b.

Ge((Operand, Operand))

a >= b.

Le((Operand, Operand))

a <= b.

Eq((Operand, Operand))

a == b.

Ne((Operand, Operand))

a != b.

CrossAbove((Operand, Operand))

a crosses above b this bar.

CrossBelow((Operand, Operand))

a crosses below b this bar.

Between((Operand, Operand, Operand))

lo <= a <= hi: [a, lo, hi].

Rising((Operand, u32))

a is greater than its value n bars ago: [a, n].

Falling((Operand, u32))

a is less than its value n bars ago: [a, n].

All(Vec<Condition>)

All sub-conditions true (AND).

Any(Vec<Condition>)

Any sub-condition true (OR).

Not(Box<Condition>)

Negation.

InPosition(bool)

True iff a position is currently open.

BarsSinceEntry(IntPredicate)

Predicate on the number of bars since entry.

Trait Implementations

impl Clone for Condition

fn clone(&self) -> Condition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Condition

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Condition

fn deserialize<__D>( __deserializer: __D, ) -> Result<Condition, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for Condition

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for Condition

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for Condition

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,
