    pub content_type: String,
    pub size: usize,
    pub data: Bytes,
}

A single uploaded file extracted from a multipart request.

Fields

name: String

Original file name from the upload.

content_type: String

data: Bytes

Implementations

impl UploadedFile

pub async fn from_field(field: Field) -> Result<Self>

Build an UploadedFile by consuming an axum multipart field.

Reads the entire field body into memory. Prefer using MultipartRequest rather than calling this directly; it is public for advanced use cases that need to process fields individually.

Errors

Returns a 400 Bad Request error if the field body cannot be read.

pub fn extension(&self) -> Option<String>

Returns the file extension from the original filename in lowercase, without the leading dot.

Returns None if the filename has no extension (e.g. "readme") or is empty. For compound extensions such as "archive.tar.gz", only the last component ("gz") is returned.

pub fn validate(&self) -> UploadValidator<'_>

Start building a fluent validation chain for this file.

Returns an UploadValidator that can be used to check size and content type. Call UploadValidator::check to finalize and collect any violations.
