Expand description
This crate provides a single macro to help skipping a error in a loop, possibly logging it.
For example, imagine you have some code like this.
ⓘ
for string_number in &["1", "2", "three", "4"] {
let number: u32 = match string_number.parse() {
Ok(n) => n,
Err(e) => continue,
};
}
Then you can use the macro skip_fail!
to write like this.
ⓘ
for string_number in &["1", "2", "three", "4"] {
let number: u32 = skip_fail!(string_number.parse());
}
If you want the error to be logged, you can use the feature log
. The
logging will be done in WARN level with the standard logging interface
provided by log
.
