Struct GannConfig 

pub struct GannConfig {
    pub price_levels: Vec<GannLevel>,
    pub time_levels: Vec<GannLevel>,
    pub show_grid: bool,
    pub show_fan: bool,
    pub fan_ratios: Vec<GannLevel>,
    pub fan_direction: GannFanDirection,
    pub show_arcs: bool,
    pub arc_ratios: Vec<GannLevel>,
    pub show_background: bool,
    pub background_opacity: u8,
    pub show_angles: bool,
}

Levels, fan lines and arcs of the Gann tools, and the background between them.

A field missing from a saved object takes the value of GannConfig::for_tool for the tool of the Drawing that holds it, or of GannConfig::default when the object is read on its own.

Fields

price_levels: Vec<GannLevel>

Price levels counted from the first anchor: for a Gann box a fraction of its height from 0 to 1, for a Gann square or fixed square units from 0 to 5. Others are not drawn.

time_levels: Vec<GannLevel>

Time levels counted from the first anchor, read as price_levels are.

show_grid: bool

Whether a Gann square draws its price and time levels.

show_fan: bool

Whether a Gann square draws its fan lines.

fan_ratios: Vec<GannLevel>

Fan lines of a Gann square, and the lines of a Gann fan: price units per time unit, where 1 is the 1x1 line. Values must be positive and finite.

fan_direction: GannFanDirection

The corners the fan lines of a Gann square start from.

show_arcs: bool

Whether a Gann square draws its arcs.

arc_ratios: Vec<GannLevel>

Arcs of a Gann square around its first anchor, as radii in units. Values must be positive and finite; the part outside the square is not drawn.

show_background: bool

Whether bands are tinted: between the levels of a box, the arcs of a square and the lines of a fan, each in the colour of the band’s outer line.

background_opacity: u8

Band opacity, from 0 to 255.

show_angles: bool

Whether a Gann box draws rays from its corners to the level points on its far edges.

Implementations

impl GannConfig

pub fn for_tool(tool: DrawingToolType) -> Self

The levels, fan lines and arcs a new Gann box, square, fixed square or fan starts from, which a drawing without Drawing::gann draws. Start a configuration from the drawing’s own tool here rather than from GannConfig::default, which is the Gann box’s.

Trait Implementations

impl Clone for GannConfig

fn clone(&self) -> GannConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GannConfig

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

Formats the value using the given formatter.

impl Default for GannConfig

fn default() -> Self

The Gann box’s configuration, as GannConfig::for_tool gives it. A Gann square, fixed square or fan reads its levels or fan lines differently and starts from for_tool of its own tool.

impl<'de> Deserialize<'de> for GannConfig

where GannConfig: Default,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for GannConfig

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for GannConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
