rustHow to filter a vector of strings in Rust
To filter a vector of strings in Rust, you can use the filter()
method. This method takes a closure as an argument, which is used to determine which elements of the vector should be kept. The closure should return a boolean value, with true
indicating that the element should be kept and false
indicating that it should be discarded. For example, the following code will filter a vector of strings to only include strings that are longer than 5 characters:
let strings = vec!["foo", "bar", "baz", "quux"];
let filtered_strings = strings.filter(|s| s.len() > 5);
The output of this code will be a vector containing only the strings "baz"
and "quux"
.
For more information on the filter()
method, see the Rust documentation. Additionally, the Rust by Example page provides a more detailed example of how to use the filter()
method.
