Struct Attachment 

pub struct Attachment {
    pub filename: String,
    pub content_type: String,
    pub bytes: Vec<u8>,
    pub content_id: Option<String>,
}

A single file attached to an outgoing message.

Backends that have attachment size limits (SES: 40 MB per message) surface violations via MailerError::Rejected.

Fields

filename: String

Filename shown to the recipient (e.g., invoice.pdf).

content_type: String

MIME type (e.g., application/pdf). Defaults to application/octet-stream if empty.

bytes: Vec<u8>

Raw attachment bytes. For large attachments, transports are free to stream from a temp file; the API hands over owned bytes for simplicity.

content_id: Option<String>

Optional Content-ID for inline attachments referenced from HTML bodies (<img src="cid:...">). None means a regular non-inline attachment.

Trait Implementations

impl Clone for Attachment

fn clone(&self) -> Attachment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Attachment

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Attachment

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Attachment

fn eq(&self, other: &Attachment) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Attachment

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Attachment
