Enum TrustDepth 

pub enum TrustDepth {
    None,
    Limited(u8),
    Unlimited,
}

The “trust depth” of a Delegation.

See https://www.rfc-editor.org/rfc/rfc9580.html#name-trust-signature

Variants

None

Encoded as 0 on the wire

Limited(u8)

Can only be 1..=254

Unlimited

encoded as 255 on the wire

Implementations

impl TrustDepth

pub fn minus(&self, n: u8) -> Option<TrustDepth>

Subtract n from this TrustDepth

Returns None if the subtraction underflows

impl TrustDepth

pub fn acceptable_path_len(&self, path_len: usize) -> bool

Check if the length of a path is acceptable relative to this TrustDepth.

For limited trust depth, path_len must be below the depth limit. However, for TrustDepth::Unlimited any path length is acceptable.

Trait Implementations

impl Clone for TrustDepth

fn clone(&self) -> TrustDepth

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TrustDepth

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

Formats the value using the given formatter.

impl From<TrustDepth> for u8

fn from(value: TrustDepth) -> Self

Converts to this type from the input type.

impl From<u8> for TrustDepth

fn from(value: u8) -> Self

Converts to this type from the input type.

impl Hash for TrustDepth

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 Ord for TrustDepth

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TrustDepth

fn eq(&self, other: &TrustDepth) -> 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 PartialOrd for TrustDepth

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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