Struct ContentDisposition

pub struct ContentDisposition;

Defines the disposition of a multipart part it is used on (rfc2183)

This is meant to be used as a header for a multipart body part, which was created from a resource, mainly a file.

Examples are attachments like images, etc.

Possible Dispositions are:

• Inline
• Attachment

Additional it is used to provide following information as parameters:

• filename: the file name associated with the resource this body is based on
• creation-date: when the resource this body is based on was created
• modification-date: when the resource this body is based on was last modified
• read-date: when the resource this body is based on was read (to create the body)
• size: the size this resource should have, note that Content-Size is NOT a mail related header but specific to http.

Trait Implementations

impl Clone for ContentDisposition

fn clone(&self) -> ContentDisposition

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for ContentDisposition

fn default() -> ContentDisposition

Returns the “default value” for a type.

impl HeaderKind for ContentDisposition

const MAX_ONE: bool = true

I true this will assure that the header is at most one time in a header map.

const VALIDATOR: Option<HeaderMapValidator> = { None }

A function which is meant to be called with a reference to the final header map before encoding the headers. It is meant to be used do some of the contextual validations, like e.g. a From header might return a function which checks if the From header has multiple mailboxes and if so checks if there is a Sender header

type Component = Disposition

the component representing the header-field, e.g. Unstructured for Subject

fn name() -> HeaderName

a method returning the header name

fn auto_body<H>(body: H) -> Result<Header<Self>, ComponentCreationError>

where H: HeaderTryInto<Self::Component>,

Creates a Header instance automatically converting given body to the right type.

fn body(body: Self::Component) -> Header<Self>

Creates a Header instance for this header kind with given body.
