Struct MimeGuessLayer 

#[non_exhaustive]
pub struct MimeGuessLayer {}

Available on crate feature layers-mime-guess only.

MimeGuessLayer sets Content-Type from a path’s file extension.

MimeGuess

This layer uses mime_guess to automatically set Content-Type based on the file extension in the operation path.

The layer preserves any content_type that callers or services set.

For example, object storage services often return content_type from stat. In that case, the layer keeps the service’s value and skips MIME guessing.

The Fs service might omit content_type from stat, so the layer derives a value from the path’s extension.

The layer cannot infer every custom or uncommon extension. It leaves content_type empty when mime_guess::from_path::first_raw returns None.

Examples

let _ = Operator::new(services::Memory::default())?
    .layer(MimeGuessLayer::new());
