Struct FormattedHelloWorld 

pub struct FormattedHelloWorld<'l> {
    data: &'l HelloWorld<'l>,
}

A formatted hello world message. Implements Writeable.

For an example, see HelloWorldFormatter.

Fields

data: &'l HelloWorld<'l>

Implementations

impl FormattedHelloWorld<'_>

pub fn to_string(&self) -> String

Converts the given value to a String.

Under the hood, this uses an efficient Writeable implementation.

If you don’t need an allocated String, but e.g. need to write this to some sink, it is more efficient to use Writeable directly.

Trait Implementations

impl<'l> Debug for FormattedHelloWorld<'l>

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

Formats the value using the given formatter.

impl Display for FormattedHelloWorld<'_>

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

Formats the value using the given formatter.

impl Writeable for FormattedHelloWorld<'_>

fn write_to<W: Write + ?Sized>(&self, sink: &mut W) -> Result

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 write_to_parts<S: PartsWrite + ?Sized>(&self, sink: &mut S) -> Result

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 writeable_length_hint(&self) -> LengthHint

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

fn writeable_borrow(&self) -> Option<&str>

Returns a &str that matches the output of write_to, if possible.

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

Creates a new string with the data from this Writeable.
