Struct LocaleTimeFormatter 

pub struct LocaleTimeFormatter {
    pub locale: String,
    pub use_24_hour: bool,
    pub show_seconds: bool,
    pub date_format: Option<String>,
}

Locale-aware time formatter: month and weekday names and the AM/PM marker in the locale’s language, laid out as DefaultTimeFormatter does.

The names need the locales cargo feature, on by default; without it they are English, as with an unknown locale.

Fields

locale: String

Locale identifier: language and region, such as "en-US", "ja-JP" or "de-DE" ("de_DE" also works). Unknown identifiers use English names.

use_24_hour: bool

Whether to use 24-hour format

show_seconds: bool

Whether to show seconds

date_format: Option<String>

strftime pattern for the date in crosshair and tooltip labels; see DefaultTimeFormatter::date_format.

Implementations

pub fn new(locale: impl Into<String>) -> Self

Create a new locale-aware formatter

Trait Implementations

impl Clone for LocaleTimeFormatter

fn clone(&self) -> LocaleTimeFormatter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LocaleTimeFormatter

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

Formats the value using the given formatter.

impl TimeFormatter for LocaleTimeFormatter

fn format(&self, time: DateTime<Utc>, mark_type: TickMarkType) -> String

Format a ts into a display string

fn format_crosshair(&self, time: DateTime<Utc>, bar_seconds: i64) -> String

Formats the hovered bar, retaining this formatter’s date and clock conventions.

fn clone_box(&self) -> Box<dyn TimeFormatter>

Clone this formatter into a Box

fn format_tick(&self, context: TickMarkContext<'_>) -> Option<String>

Formats one axis tick with the active chart locale and display-time fields.

fn wall_time(&self, time: DateTime<Utc>) -> DateTime<Utc>
