This patch adds tests for Rust 1.54.0, 1.55.0 and 1.56.0. To make the tests pass, we have to take care of some changes like more details elements and changed heading levels. To make it easier to generate the tests for new Rust versions, we also add two bash scripts that take care of that.

SYNOPSIS
|
||
macro_rules! anyhow {
|
||
($msg : literal $(,) ?) => { ... };
|
||
($err : expr $(,) ?) => { ... };
|
||
($fmt : expr, $($arg : tt) *) => { ... };
|
||
}
|
||
|
||
DESCRIPTION
|
||
Construct an ad-hoc error from a string or existing non-`anyhow` error value.
|
||
|
||
This evaluates to an `Error`. It can take either just a string, or a format string with
|
||
arguments. It also can take any custom type which implements `Debug` and `Display`.
|
||
|
||
If called with a single argument whose type implements `std::error::Error` (in addition to
|
||
`Debug` and `Display`, which are always required), then that Error impl’s `source` is
|
||
preserved as the `source` of the resulting `anyhow::Error`.
|
||
|
||
# Example
|
||
|
||
`use anyhow::{anyhow, Result};
|
||
fn lookup(key: &str) -> Result<V> {
|
||
if key.len() != 16 {
|
||
return Err(anyhow!("key length must be 16 characters, got {:?}", key));
|
||
}
|
||
// ...
|
||
}`
