AssetLoader panics when trying to open a file with no extension #576
Description
in 0.2.1, trying to open a file with no extension causes a panic somewhere in the asset loading pipeline, even when the asset loader used has an empty string in it's extensions(&self) -> &[&str]] value. Not all files have an extension, so it should be possible to open these files, even if it means creating your own AssetLoader. Below is the asset loader that doesn't work. I don't even think it runs, if I place a panic with a specific message in the from_bytes function, the other panics happen before.
#[derive(Default)]
struct Test;
impl AssetLoader<Test> for Test
{
fn from_bytes(&self, _asset_path: &Path, bytes: Vec<u8>) -> Result<Test, Error>
{
Ok(Test)
}
fn extensions(&self) -> &[&str]
{
&[""]
}
}(as an aside, I think it should be possible to open files that don't match their loader's extensions, as some more general types could accept almost any type, like a loader for Vec<u8> or String)
