Struct mod_utilities::FMTAdaptor

pub struct FMTAdaptor<'a> {
    pub error: Option<Error>,
    // some fields omitted
}

A shim which translates an io::Write to a fmt::Write

If an error occurs with the inner io::Write, it is stored in an optional member, and all further calls to fmt::Write will be short circuited until it is cleared

Safety

• Does not call flush
• Adapting an adaptor would cause all sorts of problems

Fields

error: Option<Error>

If an io error occurs while using a FMTAdaptor, it will be stored here and block further usage until it is resolved

Trait Implementations

impl<'a> Write for FMTAdaptor<'a>

fn write_str(&mut self, s: &str) -> Result

Writes a string slice into this writer, returning whether the write succeeded.

fn write_char(&mut self, c: char) -> Result<(), Error>

Writes a [char] into this writer, returning whether the write succeeded.

fn write_fmt(&mut self, args: Arguments) -> Result<(), Error>

Glue for usage of the [write!] macro with implementors of this trait.
