Enum FileRejection 

#[non_exhaustive]
pub enum FileRejection {
    Extension,
    ContentType,
    TooLarge,
    TooMany,
}

Why a file was rejected by a FileFilter.

Non-exhaustive: new acceptance rules mean new rejection reasons, so keep a wildcard arm with a generic “not accepted” message.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Extension

Extension not in the allow-list.

ContentType

MIME type not in the allow-list.

TooLarge

Larger than max_size bytes.

TooMany

Batch exceeded max_files; this file was over the limit.
