Struct InputFileRef 

pub struct InputFileRef {
    pub attach_name: Option<String>,
    pub bytes: Vec<u8>,
    pub mime_type: Option<String>,
    pub file_name: Option<String>,
}

Metadata for a single file that is uploaded as part of a multipart form.

The attach_name is the name used in the attach://<name> URI scheme. When it is None the file must be sent as the sole binary part and the parameter value itself is omitted from the JSON payload (matching the Python if value.attach_uri branch).

Fields

attach_name: Option<String>

Multipart form part name. When present the JSON value is "attach://<attach_name>". When absent the file is sent directly and the parameter’s JSON value is None.

bytes: Vec<u8>

Raw file bytes.

mime_type: Option<String>

Optional MIME type (defaults to application/octet-stream).

file_name: Option<String>

Optional file name hint sent to Telegram.

Implementations

impl InputFileRef

pub fn direct(bytes: Vec<u8>) -> Self

Build an InputFileRef that is uploaded directly (no attach URI).

pub fn with_attach_name(attach_name: impl Into<String>, bytes: Vec<u8>) -> Self

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

The attach:// URI string, if this file has an attach name.

pub fn effective_mime(&self) -> &str

The MIME type string used when building the multipart part, falling back to application/octet-stream.
