Struct ChangeSet

pub struct ChangeSet {
    pub blocks: BTreeMap<u32, Option<BlockHash>>,
}

The ChangeSet represents changes to LocalChain.

Fields

blocks: BTreeMap<u32, Option<BlockHash>>

Changes to the LocalChain blocks.

The key represents the block height, and the value either represents added a new CheckPoint (if Some), or removing a CheckPoint (if None).

Implementations

impl ChangeSet

pub const SCHEMA_NAME: &'static str = "bdk_localchain"

Schema name for the changeset.

pub const BLOCKS_TABLE_NAME: &'static str = "bdk_blocks"

Name of sqlite table that stores blocks of LocalChain.

pub fn schema_v0() -> String

Get v0 of sqlite local_chain::ChangeSet schema

pub fn init_sqlite_tables(db_tx: &Transaction<'_>) -> Result<()>

Initialize sqlite tables for persisting local_chain::LocalChain.

pub fn from_sqlite(db_tx: &Transaction<'_>) -> Result<Self>

Construct a LocalChain from sqlite database.

Remember to call Self::init_sqlite_tables beforehand.

pub fn persist_to_sqlite(&self, db_tx: &Transaction<'_>) -> Result<()>

Persist changeset to the sqlite database.

Remember to call Self::init_sqlite_tables beforehand.

Trait Implementations

impl Clone for ChangeSet

fn clone(&self) -> ChangeSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChangeSet

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

Formats the value using the given formatter.

impl Default for ChangeSet

fn default() -> ChangeSet

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ChangeSet

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<B: IntoIterator<Item = (u32, Option<BlockHash>)>> From<B> for ChangeSet

fn from(blocks: B) -> Self

Converts to this type from the input type.

impl FromIterator<(u32, BlockHash)> for ChangeSet

fn from_iter<T: IntoIterator<Item = (u32, BlockHash)>>(iter: T) -> Self

Creates a value from an iterator.

impl FromIterator<(u32, Option<BlockHash>)> for ChangeSet

fn from_iter<T: IntoIterator<Item = (u32, Option<BlockHash>)>>(iter: T) -> Self

Creates a value from an iterator.

impl Merge for ChangeSet

fn merge(&mut self, other: Self)

Merge another object of the same type onto self.

fn is_empty(&self) -> bool

Returns whether the structure is considered empty.

fn take(&mut self) -> Option<Self>

Take the value, replacing it with the default value.

impl PartialEq for ChangeSet

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
