Enum DocHeightRequest 

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

for some reason bincode does not allow deserialize_any so if i want to allow end users to type “top”, 42, or “persist” i need to do have to copies of this where one is not untagged.

bincode. please.

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

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

Convert the data to a byte vector

impl Debug for DocHeightRequest

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

Formats the value using the given formatter.

impl Default for DocHeightRequest

fn default() -> DocHeightRequest

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DocHeightRequest

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 FromStr for DocHeightRequest

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for DocHeightRequest

fn eq(&self, other: &DocHeightRequest) -> 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.

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
