pub struct ConcatTryWriter<F1>(_);
Expand description

A writer that calls write_str once with a combined string.

Write function can return either () or for<T, E> Result<T, E>.

Writer propagates error to the caller if the write function returns Result::Err.

Implementations§

source§

impl<F1> ConcatTryWriter<F1>where F1: WriteStr,

source

pub fn new(write: F1) -> Self

Creates a new ConcatTryWriter from an object that implements WriteStr.

source

pub fn from_closure<F, Ts>(closure: F) -> Selfwhere F: IntoTryWriteFn<Ts, TryWriteFn = F1>,

Creates a new ConcatTryWriter with a WriteStr wrapper deduced with IntoTryWriteFn by the closure signature and constructed from it.

source§

impl<F1> ConcatTryWriter<F1>where Self: WriteStr,

source

pub fn write_fmt(&mut self, args: Arguments<'_>) -> <Self as WriteStr>::Output

Writes a formatted string into this writer, returning any error encountered.

This method is primarily used to interface with the format_args! macro, but it is rare that this should explicitly be called. The write! macro should be favored to invoke this method instead.
