Struct LightBlock 

pub struct LightBlock {
    pub signed_header: SignedHeader,
    pub validators: ValidatorSet,
    pub next_validators: ValidatorSet,
    pub provider: PeerId,
}

A light block is the core data structure used by the light client. It records everything the light client needs to know about a block.

Fields

signed_header: SignedHeader

Header and commit of this block

validators: ValidatorSet

Validator set at the block height

next_validators: ValidatorSet

Validator set at the next block height

provider: PeerId

The peer ID of the node that provided this block

Implementations

impl LightBlock

pub fn new( signed_header: SignedHeader, validators: ValidatorSet, next_validators: ValidatorSet, provider: PeerId, ) -> LightBlock

Constructs a new light block

pub fn height(&self) -> Height

Returns the height of this block.

Note

This is a shorthand for block.signed_header.header.height.

pub fn time(&self) -> Time

Returns the time at which this block was created.

Note

This is a shorthand for block.signed_header.header.time.

pub fn as_trusted_state(&self) -> TrustedBlockState<'_>

Obtain the verification parameters for the light block when using it as trusted state.

pub fn as_untrusted_state(&self) -> UntrustedBlockState<'_>

Obtain the verification parameters for the light block when using it as untrusted state.

Trait Implementations

impl Clone for LightBlock

fn clone(&self) -> LightBlock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LightBlock

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LightBlock

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for LightBlock

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

Formats the value using the given formatter.

impl Eq for LightBlock

impl PartialEq for LightBlock

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
