Enum HeightRequest 

pub enum HeightRequest {
    Top,
    Absolute(u32),
    Checkpoint(RetentionSpan),
}

Variants

Top

Use the latest height for the ledger

Absolute(u32)

Set the height to the given block (there must be a checkpoint at this height) Setting to 0 will reset the height to the genesis block

Checkpoint(RetentionSpan)

Use the next checkpoint that matches this checkpoint span

Implementations

impl HeightRequest

pub fn is_top(&self) -> bool

pub fn reset(&self) -> bool

Trait Implementations

impl Clone for HeightRequest

fn clone(&self) -> HeightRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DataFormat for HeightRequest

const LATEST_HEADER: Self::Header

type Header = (u8, <RetentionSpan as DataFormat>::Header)

fn write_data<W: Write>(&self, writer: &mut W) -> Result<usize, DataWriteError>

Write the data to the writer

fn read_data<R: Read>( reader: &mut R, header: &Self::Header, ) -> Result<Self, DataReadError>

Read the data from the reader

fn write_header<W: Write>( &self, writer: &mut W, ) -> Result<usize, DataWriteError>

fn read_header<R: Read>(reader: &mut R) -> Result<Self::Header, DataReadError>

fn to_byte_vec(&self) -> Result<Vec<u8>, DataWriteError>

Convert the data to a byte vector

impl Debug for HeightRequest

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

Formats the value using the given formatter.

impl Default for HeightRequest

fn default() -> HeightRequest

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for HeightRequest

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<DocHeightRequest> for HeightRequest

fn from(req: DocHeightRequest) -> Self

Converts to this type from the input type.

impl PartialEq for HeightRequest

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for HeightRequest
