Enum PrincipalNeed 

pub enum PrincipalNeed {
    Nothing,
    Identity,
    Chain,
}

How much a statement’s scope says about principal, and therefore how much the gate must know about the account for the statement to be judged at all.

Variants

Nothing

principal is unconstrained.

Identity

principal == or principal is: the account’s identity.

Chain

principal in: the account’s admission chain.

Implementations

impl PrincipalNeed

fn of(constraint: &PrincipalConstraint) -> Self

Trait Implementations

impl Clone for PrincipalNeed

fn clone(&self) -> PrincipalNeed

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrincipalNeed

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

Formats the value using the given formatter.

impl Display for PrincipalNeed

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

Formats the value using the given formatter.

impl Ord for PrincipalNeed

fn cmp(&self, other: &PrincipalNeed) -> 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 PrincipalNeed

fn eq(&self, other: &PrincipalNeed) -> 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 PrincipalNeed

fn partial_cmp(&self, other: &PrincipalNeed) -> 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.
