Struct ParamSpec 

pub struct ParamSpec {
    pub name: &'static str,
    pub kind: ParamKind,
    pub default: f64,
    pub min: f64,
    pub max: f64,
}

A single tunable parameter of an indicator.

default, min and max are all f64 regardless of ParamKind so the serialized JSON has a uniform numeric shape; for Integer params the values are whole numbers stored as f64 (e.g. 14.0).

Fields

name: &'static str

Parameter key — matches the key the indicator’s factory() reads (e.g. "period", "fast_period", "std_dev").

kind: ParamKind

Whether the UI should treat this as an integer or a float control.

default: f64

Default value — must equal the factory’s default and lie in [min, max].

min: f64

Inclusive lower bound for the UI control.

max: f64

Inclusive upper bound for the UI control.

Implementations

impl ParamSpec

pub const fn int(name: &'static str, default: f64, min: f64, max: f64) -> Self

Construct an ParamKind::Integer parameter spec.

pub const fn float(name: &'static str, default: f64, min: f64, max: f64) -> Self

Construct a ParamKind::Float parameter spec.

Trait Implementations

impl Clone for ParamSpec

fn clone(&self) -> ParamSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ParamSpec

impl Debug for ParamSpec

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

Formats the value using the given formatter.

impl Deserialize<'static> for ParamSpec

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'static>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ParamSpec

fn eq(&self, other: &ParamSpec) -> 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.

impl Serialize for ParamSpec

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
