Enum Tree 

pub enum Tree {
    Standards,
    Vendor,
    Personal,
    Private,
    Unregistered(Cow<'static, str>),
}

Provides the four registration trees.

Variants

Standards

The standards tree is intended for types of general interest to the Internet community.

Vendor

The vendor tree is used for media types associated with publicly available products.

Personal

Registrations for media types created experimentally or as part of products that are not distributed commercially may be registered in the personal or vanity tree.

Private

Subtype names with “x.” as the first facet may be used for types intended exclusively for use in private, local environments.

Unregistered(Cow<'static, str>)

Other unofficial trees.

Trait Implementations

impl Clone for Tree

fn clone(&self) -> Tree

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tree

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

Formats the value using the given formatter.

impl Display for Tree

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

Formats the value using the given formatter.

impl PartialEq for Tree

fn eq(&self, other: &Tree) -> 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 Eq for Tree

impl StructuralPartialEq for Tree
