Enum rasn::TagTree

pub enum TagTree {
    Leaf(Tag),
    Choice(&'static [TagTree]),
}

The root or node in tree representing all of potential tags in a ASN.1 type. For most types this is only ever one level deep, except for CHOICE enums which will contain a set of nodes, that either point to a Leaf or another level of Choice.

Variants

Leaf(Tag)

The end of branch in the tree.

Choice(&'static [TagTree])

A branch in the tree.

Implementations

impl TagTree

pub const fn empty() -> Self

pub const fn smallest_tag(&self) -> Tag

pub const fn is_unique(&self) -> bool

Returns whether a given TagTree only contains unique entries.

pub const fn tag_contains(needle: &Tag, nodes: &[TagTree]) -> bool

Whether needle matches any Leafs in nodes.

Trait Implementations

impl Clone for TagTree

fn clone(&self) -> TagTree

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TagTree

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

Formats the value using the given formatter.

impl Ord for TagTree

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for TagTree

fn eq(&self, other: &TagTree) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for TagTree

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
