Struct runtime_fmt::PreparedFormat

pub struct PreparedFormat<'s, T: FormatArgs> { /* fields omitted */ }

A pre-checked format string, ready for values of a specific type to be formatted against it.

Methods

impl<'s, T: FormatArgs> PreparedFormat<'s, T>

pub fn prepare(spec: &'s str) -> Result<Self, Error>

Prepare a format string against a formattable type.

Once the format string has been prepared, formatting individual values will not require checking the validity of the format string over again.

pub fn newln(&mut self) -> &mut Self

Append a linefeed (\n) to the end of this buffer.

pub fn with<F: FnOnce(Arguments) -> R, R>(&self, t: &T, f: F) -> R

Call a function accepting Arguments with the contents of this buffer.

pub fn format(&self, t: &T) -> String

Format the given value to a String.

pub fn print(&self, t: &T)

Print the given value to standard output.

pub fn write_io<W: Write + ?Sized>(&self, t: &T, dest: &mut W) -> Result<()>

Write the given value to an io::Write.

pub fn write_fmt<W: Write + ?Sized>(&self, t: &T, dest: &mut W) -> Result

Write the given value to a fmt::Write.
