Struct WitnessRef 

pub struct WitnessRef {
    pub accepted_root: String,
    pub chain: Vec<String>,
}

A witness that one content-addressed state descends from another through the recorded branch and partial-checkpoint chain.

Fields

accepted_root: String

The accepted root the chain must reach.

chain: Vec<String>

State roots from the seed back to the accepted root, oldest last.

Implementations

impl WitnessRef

pub fn root(accepted_root: impl Into<String>) -> Self

A root branch’s trivial witness: the seed is the accepted root.

pub fn reaches(&self, accepted_root: &str) -> bool

Whether the chain reaches the given accepted root.

pub fn extend(&self, child_root: impl Into<String>) -> Self

Extend the chain with a child checkpoint root.

Trait Implementations

impl Clone for WitnessRef

fn clone(&self) -> WitnessRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WitnessRef

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for WitnessRef

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for WitnessRef

fn eq(&self, other: &WitnessRef) -> 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 Serialize for WitnessRef

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
