1.0.0[−][src]Struct sgx_tstd::fmt::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.
An important thing to remember is that the type fmt::Error
should not be
confused with std::io::Error
or std::error::Error
, which you may also
have in scope.
Examples
use std::fmt::{self, write}; let mut output = String::new(); if let Err(fmt::Error) = write(&mut output, format_args!("Hello {}!", "world")) { panic!("An error occurred"); }

Pending CVE number here https://github.com/rust-lang/rust/issues/60784 Alex said: This leaves us, however, with the question of what to do about this API? Error::type_id has been present since the inception of the Error trait, all the way back to 1.0.0. It's unstable, however, and is pretty rare as well to have a manual implementation of the type_id function. Despite this we would ideally still like a path to stability which includes safety at some point. Read more
