Struct MessageHeader 

#[non_exhaustive]
pub struct MessageHeader {
    pub name: Option<String>,
    pub value: Option<String>,
}

Contains the name and value pair of an email header to add to your email. You can have up to 15 MessageHeaders. A header can contain information such as the sender, receiver, route, or timestamp.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: Option<String>

The name of the message header. The header name can contain up to 126 characters.

value: Option<String>

The value of the message header. The header value can contain up to 870 characters, including the length of any rendered attributes. For example if you add the {CreationDate} attribute, it renders as YYYY-MM-DDTHH:MM:SS.SSSZ and is 24 characters in length.

Implementations

impl MessageHeader

pub fn name(&self) -> Option<&str>

The name of the message header. The header name can contain up to 126 characters.

pub fn value(&self) -> Option<&str>

The value of the message header. The header value can contain up to 870 characters, including the length of any rendered attributes. For example if you add the {CreationDate} attribute, it renders as YYYY-MM-DDTHH:MM:SS.SSSZ and is 24 characters in length.

impl MessageHeader

pub fn builder() -> MessageHeaderBuilder

Creates a new builder-style object to manufacture MessageHeader.

Trait Implementations

impl Clone for MessageHeader

fn clone(&self) -> MessageHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageHeader

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

Formats the value using the given formatter.

impl PartialEq for MessageHeader

fn eq(&self, other: &MessageHeader) -> 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.
