pub struct RelativeTimeFormatter {
    pub reference_time: DateTime<Utc>,
}

Relative time formatter (e.g., “2h ago”, “yesterday”)

Fields

Reference time for relative calculations (usually “now”)

Implementations

impl RelativeTimeFormatter

pub fn new(reference_time: DateTime<Utc>) -> Self

Create a new relative time formatter

pub fn now() -> Self

Create a formatter relative to current time

Trait Implementations

impl Clone for RelativeTimeFormatter

fn clone(&self) -> RelativeTimeFormatter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RelativeTimeFormatter

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

Formats the value using the given formatter.

impl TimeFormatter for RelativeTimeFormatter

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

Format a ts into a display string

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>

Clock-face time used to identify calendar boundaries. The returned UTC value holds local fields, not another instant.

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

Converts local calendar fields from wall_time back to an instant. Repeated times use the first instant; skipped times use the clock jump.

fn time_visible(&self) -> bool

Whether intraday marks and hover labels include the clock.

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

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