Struct EmailHeader 

#[non_exhaustive]
pub struct EmailHeader {
    pub name: String,
    pub value: String,
    pub extra: Map<String, Value>,
}

A single RFC 5322 header field (RFC 8621 §4.1.3).

The name retains original capitalisation; value is the raw field value.

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: String

The header field name (e.g. "Content-Type"), case-preserved.

value: String

The header field value in Raw form.

extra: Map<String, Value>

Catch-all for vendor / site / private extension fields not covered by the typed fields above. Preserves unknown fields across deserialize/serialize round-trip per workspace extras-preservation policy (see workspace AGENTS.md).

Implementations

impl EmailHeader

pub fn new(name: impl Into<String>, value: impl Into<String>) -> Self

Construct an EmailHeader from its name and value.

Trait Implementations

impl Clone for EmailHeader

fn clone(&self) -> EmailHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EmailHeader

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EmailHeader

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for EmailHeader

impl PartialEq for EmailHeader

fn eq(&self, other: &EmailHeader) -> 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 EmailHeader

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
