Struct icu::datetime::FormattedDateTime

pub struct FormattedDateTime<'a> { /* private fields */ }

An intermediate type during a datetime formatting operation.

Not intended to be stored: convert to a string first.

Implementations

impl FormattedDateTime<'_>

pub fn to_string(&self) -> String

Converts the given value to a String.

Under the hood, this uses an efficient Writeable implementation. However, in order to avoid allocating a string, it is more efficient to use Writeable directly.

impl FormattedDateTime<'_>

pub fn pattern(&self) -> DateTimePattern

Gets the pattern used in this formatted value.

From the pattern, one can check the properties of the included components, such as the hour cycle being used for formatting. See DateTimePattern.

Trait Implementations

impl<'a> Debug for FormattedDateTime<'a>

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

Formats the value using the given formatter.

impl Display for FormattedDateTime<'_>

This trait is implemented for compatibility with fmt!. To create a string, Writeable::write_to_string is usually more efficient.

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

Formats the value using the given formatter.

impl Writeable for FormattedDateTime<'_>

fn write_to_parts<S>(&self, sink: &mut S) -> Result<(), Error>

where S: PartsWrite + ?Sized,

Write bytes and Part annotations to the given sink. Errors from the sink are bubbled up. The default implementation delegates to write_to, and doesn’t produce any Part annotations.

fn write_to<W>(&self, sink: &mut W) -> Result<(), Error>

where W: Write + ?Sized,

Writes a string to the given sink. Errors from the sink are bubbled up. The default implementation delegates to write_to_parts, and discards any Part annotations.

fn writeable_length_hint(&self) -> LengthHint

Returns a hint for the number of UTF-8 bytes that will be written to the sink.

fn write_to_string(&self) -> Cow<'_, str>

Creates a new String with the data from this Writeable. Like ToString, but smaller and faster.
