Enum PartSpecifier

pub enum PartSpecifier<'a> {
    PartNumber(u32),
    Header,
    HeaderFields(NonEmptyVec<AString<'a>>),
    HeaderFieldsNot(NonEmptyVec<AString<'a>>),
    Mime,
    Text,
}

A part specifier is either a part number or one of the following: HEADER, HEADER.FIELDS, HEADER.FIELDS.NOT, MIME, and TEXT.

The HEADER, HEADER.FIELDS, and HEADER.FIELDS.NOT part specifiers refer to the [RFC-2822] header of the message or of an encapsulated [MIME-IMT] MESSAGE/RFC822 message. HEADER.FIELDS and HEADER.FIELDS.NOT are followed by a list of field-name (as defined in [RFC-2822]) names, and return a subset of the header.

The field-matching is case-insensitive but otherwise exact. Subsetting does not exclude the [RFC-2822] delimiting blank line between the header and the body; the blank line is included in all header fetches, except in the case of a message which has no body and no blank line.

Trait Implementations

impl<'a> Clone for PartSpecifier<'a>

fn clone(&self) -> PartSpecifier<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for PartSpecifier<'a>

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

Formats the value using the given formatter.

impl<'de, 'a> Deserialize<'de> for PartSpecifier<'a>

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> Hash for PartSpecifier<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> IntoBoundedStatic for PartSpecifier<'a>

type Static = PartSpecifier<'static>

The target type is bounded by the 'static lifetime.

fn into_static(self) -> Self::Static

Convert an owned T into an owned T such that T: 'static.

impl<'a> PartialEq for PartSpecifier<'a>

fn eq(&self, other: &PartSpecifier<'a>) -> 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<'a> Serialize for PartSpecifier<'a>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'a> ToBoundedStatic for PartSpecifier<'a>

type Static = PartSpecifier<'static>

The target type is bounded by the 'static lifetime.

fn to_static(&self) -> Self::Static

Convert an &T to an owned T such that T: 'static.

impl<'a> Eq for PartSpecifier<'a>

impl<'a> StructuralPartialEq for PartSpecifier<'a>
