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

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§

source§

impl PartPointer

source

pub fn root() -> Self

Construct a PartPointer that references the root node

source

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

source

pub fn nth(n: u8) -> Self

Construct a PartPointer that references the nth child

source

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

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