Enum ChartSettingsError 

#[non_exhaustive]
pub enum ChartSettingsError {
    Timezone(ParseError),
    Margins {
        top: f32,
        bottom: f32,
    },
    CrosshairWidth(f32),
    FontSize(u8),
    PriceToBarRatio(f64),
    ExecutionSoundVolume(f32),
    AlertSoundVolume(f32),
    ChartTypeParams {
        chart_type: ChartType,
        reason: &'static str,
    },
}

Why ChartSettingsState::apply_to_chart left the chart unchanged. Its text is the one the settings dialog shows.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Timezone(ParseError)

timezone names no time zone this build knows.

Margins

The margins are not finite, are negative or leave no room for prices.

Fields

top: f32

The top margin in percent.

bottom: f32

The bottom margin in percent.

CrosshairWidth(f32)

The crosshair line width is not finite or not above zero.

FontSize(u8)

The axis font size is zero.

PriceToBarRatio(f64)

The locked price-to-bar ratio is not finite or not above zero.

ExecutionSoundVolume(f32)

The trading execution sound volume is outside 0 to 1.

AlertSoundVolume(f32)

The alert sound volume is outside 0 to 1.

ChartTypeParams

The chart type parameters do not fit the chart type.

Fields

chart_type: ChartType

The chart type they were checked against.

reason: &'static str

Why they were refused.

Trait Implementations

impl Clone for ChartSettingsError

fn clone(&self) -> ChartSettingsError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChartSettingsError

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

Formats the value using the given formatter.

impl Display for ChartSettingsError

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

impl Error for ChartSettingsError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
