Struct PartPointer

pub struct PartPointer(/* private fields */);

References the position of a MimePart by encoding the steps in a tree walking operation. The encoding of PartPointer is a sequence of integers that identify the index of a child part by its level within the mime tree, selecting the current node when no more indices remain. eg: [] indicates the root part, while [0] is the 0th child of the root.

Implementations

impl PartPointer

pub fn root() -> Self

Construct a PartPointer that references the root node

pub fn root_or_nth(n: Option<u8>) -> Self

Construct a PartPointer that references either the nth or the root node depending upon the passed parameter

pub fn nth(n: u8) -> Self

Construct a PartPointer that references the nth child

pub fn append(self, other: Self) -> Self

Join other onto self, consuming self and producing a pointer that makes other relative to self

Trait Implementations

impl Clone for PartPointer

fn clone(&self) -> PartPointer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PartPointer

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

Formats the value using the given formatter.

impl PartialEq for PartPointer

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