This patch refactors the test suite: - Instead of always generating the documentation with the available rustdoc version, we now store generated documentation for all supported rustdoc versions in the test/html directory. - Instead of using one snapshot per test case, we now use one snapshot per test case and rustdoc version.

anyhow Macro anyhow::anyhow rusty-man

SYNOPSIS
|
|
macro_rules! anyhow {
|
|
($msg:literal $(,)?) => { ... };
|
|
($err:expr $(,)?) => { ... };
|
|
($fmt:expr, $($arg:tt)*) => { ... };
|
|
}

DESCRIPTION
|
|
Construct an ad-hoc error from a string.
|
|
|
|
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`.
|
|
|
|
# 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));
|
|
}
|
|
// ...
|
|
}
