# Struct std::fmt::Error 1.0.0 [−] [src]

    pub struct Error;

The error type which is returned from formatting a message into a stream.

This type does not support transmission of an error other than that an error occurred. Any extra information must be arranged to be transmitted through some other means.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
