Struct ChartParams 

pub struct ChartParams {
    pub chart_kind: Option<String>,
    pub chart_series: Option<String>,
    pub renderer: Option<String>,
}

Chart-specific query parameters shared across report chart handlers. chart_kind maps to plotting::ChartKind; chart_series is a report-specific toggle (e.g. Activity: show Net or not) parsed in each handler. renderer picks between server-side SVG (default) and client-side canvas.

Fields

chart_kind: Option<String>

chart_series: Option<String>

renderer: Option<String>

Implementations

impl ChartParams

pub fn chart_kind_or_default(&self) -> ChartKind

Parse chart_kind (bar, line, stacked) into a plotting::ChartKind. Unknown / missing values fall back to Bar so a stale URL still renders something.

pub fn chart_kind_str(&self) -> String

Normalise the chart kind to its canonical lowercase name so the template can round-trip it into URLs and <select> values.

pub fn renderer_str(&self) -> String

Canonicalise the renderer choice. Accepts svg (default) and canvas; anything else normalises to svg.

Trait Implementations

impl Default for ChartParams

fn default() -> ChartParams

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ChartParams

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
