Struct DatabaseMock 

pub struct DatabaseMock {
    pub data: BTreeMap<Vec<u8>, Vec<u8>>,
}

Mock database implementation for testing and development.

Provides a lightweight implementation of the Database trait suitable for testing scenarios where actual database operations are not required.

Fields

data: BTreeMap<Vec<u8>, Vec<u8>>

Internal data storage using a BTreeMap.

TODO: Make the mock database table-aware by properly utilizing this data structure to simulate realistic database behavior during testing.

Trait Implementations

impl Clone for DatabaseMock

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Database for DatabaseMock

fn tx(&self) -> Result<Self::TX, DatabaseError>

Creates a new read-only transaction.

This always succeeds and returns a default TxMock instance. The mock transaction doesn’t actually perform any database operations.

fn tx_mut(&self) -> Result<Self::TXMut, DatabaseError>

Creates a new read-write transaction.

This always succeeds and returns a default TxMock instance. The mock transaction doesn’t actually perform any database operations.

type TX = TxMock

Read-Only database transaction

type TXMut = TxMock

Read-Write database transaction

fn path(&self) -> PathBuf

Returns the path to the database directory.

fn oldest_reader_txnid(&self) -> Option<u64>

Returns the transaction ID of the oldest active reader, if available.

fn last_txnid(&self) -> Option<u64>

Returns the ID of the most recently committed transaction, if available.

fn view<T, F>(&self, f: F) -> Result<T, DatabaseError>

where F: FnOnce(&mut Self::TX) -> T,

Takes a function and passes a read-only transaction into it, making sure it’s closed in the end of the execution.

fn update<T, F>(&self, f: F) -> Result<T, DatabaseError>

where F: FnOnce(&Self::TXMut) -> T,

Takes a function and passes a write-read transaction into it, making sure it’s committed in the end of the execution.

impl DatabaseMetrics for DatabaseMock

fn report_metrics(&self)

Reports metrics for the database.

fn gauge_metrics(&self) -> Vec<(&'static str, f64, Vec<Label>)>

Returns a list of Gauge metrics for the database.

fn counter_metrics(&self) -> Vec<(&'static str, u64, Vec<Label>)>

Returns a list of Counter metrics for the database.

fn histogram_metrics(&self) -> Vec<(&'static str, f64, Vec<Label>)>

Returns a list of Histogram metrics for the database.

impl Debug for DatabaseMock

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

Formats the value using the given formatter.

impl Default for DatabaseMock

fn default() -> Self

Returns the “default value” for a type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
