Expand description

Wide-column store client abstraction (e.g. Apache HBase).

Cells are keyed by family:qualifier; values are opaque JSON values whose mapping to bytes is backend-specific.

Required Methods§

Source

fn put<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, table: &'life1 str, row: &'life2 str, cells: &'life3 BTreeMap<String, Value>, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Write cells to row in table, creating or merging the row.

Source

fn get<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, table: &'life1 str, row: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<Option<BTreeMap<String, Value>>, Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Read every cell of row; None when the row does not exist.

Source

fn scan<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, table: &'life1 str, prefix: &'life2 str, limit: usize, ) -> Pin<Box<dyn Future<Output = Result<Vec<(String, BTreeMap<String, Value>)>, Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Scan rows starting at prefix (a row-key prefix), returning at most limit rows as (row key, cells) pairs.

Source

fn delete<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, table: &'life1 str, row: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Delete row entirely.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
