## Get MIME type from filename

The following example shows how to return the correct MIME type from a given
|
||||||
|
filename using the [mime] crate. The program will check for file extensions
|
||||||
|
and match against a known list. The return value is [`mime:Mime`].
|
||||||
|
|
||||||
|
```rust
|
||||||
|
extern crate mime;
|
||||||
|
use mime::Mime;
|
||||||
|
|
||||||
|
fn find_mimetype (filename : &String) -> Mime{
|
||||||
|
|
||||||
|
let parts : Vec<&str> = filename.split('.').collect();
|
||||||
|
|
||||||
|
let res = match parts.last() {
|
||||||
|
Some(v) =>
|
||||||
|
match *v {
|
||||||
|
"png" => mime::IMAGE_PNG,
|
||||||
|
"jpg" => mime::IMAGE_JPEG,
|
||||||
|
"json" => mime::APPLICATION_JSON,
|
||||||
|
&_ => mime::TEXT_PLAIN,
|
||||||
|
},
|
||||||
|
None => mime::TEXT_PLAIN,
|
||||||
|
};
|
||||||
|
return res;
|
||||||
|
}
|
||||||
|
|
||||||
|
fn main() {
|
||||||
|
let filenames = vec!("foobar.jpg", "foo.bar", "foobar.png");
|
||||||
|
for file in filenames {
|
||||||
|
let mime = find_mimetype(&file.to_owned());
|
||||||
|
println!("MIME for {}: {}", file, mime);
|
||||||
|
}
|
||||||
|
|
||||||
|
}
|
||||||
|
```
