Struct WriteError

pub struct WriteError(/* private fields */);

Error type which converts a fmt::Error into an Artichoke Error.

This error type can also be used to convert generic fmt::Error into an Error, such as when formatting integers with write!.

This error type wraps a fmt::Error.

Examples

use std::fmt::Write;

fn task() -> Result<String, Error> {
    let mut buf = String::new();
    write!(&mut buf, "success!").map_err(WriteError::from)?;
    Ok(buf)
}

Implementations

Trait Implementations

impl Clone for WriteError

fn clone(&self) -> WriteError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for WriteError

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

Formats the value using the given formatter.

impl Display for WriteError

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

Formats the value using the given formatter.

impl Error for WriteError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
