Enum AttributePreference 

pub enum AttributePreference {
    Preferred,
    Acceptable,
}

A level of preference for a peer attribute.

Invalid peer attributes are represented as errors.

Outbound peer connections are initiated in the sorted order of this type.

The derived order depends on the order of the variants in the enum. The variants are sorted in the order they are listed.

Variants

Preferred

This peer is more likely to be a valid Zcash network peer.

Correctness

This variant must be declared as the first enum variant, so that Preferred peers sort before Acceptable peers.

Acceptable

This peer is possibly a valid Zcash network peer.

Implementations

impl AttributePreference

pub fn preferred_from(is_preferred: bool) -> Self

Returns Preferred if is_preferred is true.

pub fn is_preferred(&self) -> bool

Returns true for Preferred attributes.

Trait Implementations

impl Clone for AttributePreference

fn clone(&self) -> AttributePreference

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AttributePreference

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

Formats the value using the given formatter.

impl Ord for AttributePreference

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

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

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
