Struct TimeFormat

Source
pub struct TimeFormat { /* private fields */ }
Expand description

The style of timestamp to be formatted for tracing events.

Format strings are used by jiff::fmt::strtime, and local timezone handling is provided by the jiff crate.

Implementations§

Source§

impl TimeFormat

Source

pub const LOCAL_FORMAT: &'static str = "[%Y-%m-%dT%H:%M:%S%z]"

RFC 3339 timestamp enclosed in square brackets, with offset.

Source

pub const UTC_FORMAT: &'static str = "[%Y-%m-%dT%H:%M:%SZ]"

RFC 3339 timestamp enclosed in square brackets, with UTC (using ‘Z’ for the timezone instead of ‘+0000’)

Source

pub const fn none() -> Self

Do not render a timestamp.

Source

pub const fn local() -> Self

Render a timestamp in the local timezone using the default format.

Source

pub const fn utc() -> Self

Render a timestamp in UTC using the default format.

Source

pub fn local_custom(format: impl Into<String>) -> Self

Render a timestamp in the local timezone using a custom format.

Panics: When debug_assertions are enabled, the format string is validated to ensure that no unknown % fields are present. In release mode, formatting the timestamp fails and tracing-subscriber will emit “Unable to format the following event” messages.

Source

pub fn utc_custom(format: impl Into<String>) -> Self

Render a timestamp in UTC using a custom format.

Panics: When debug_assertions are enabled, the format string is validated to ensure that no unknown % fields are present. In release mode, formatting the timestamp fails and tracing-subscriber will emit “Unable to format the following event” messages.

Source

pub fn render(&self, ts: Timestamp) -> impl Display + '_

Get a Display-able object of this format applied to a Timestamp.

Source

pub fn render_now(&self) -> impl Display + '_

Render the current system time in this format
