Expand description

The iceberg writer used to write data to iceberg table.

Required Methods§

Source

fn write<'life0, 'async_trait>( &'life0 mut self, input: I, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Write data to iceberg table.

Source

fn close<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<O>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Close the writer and return the written data files. If close failed, the data written before maybe be lost. User may need to recreate the writer and rewrite the data again.

§NOTE

After close, regardless of success or failure, the writer should never be used again, otherwise the writer will panic.

Dyn Compatibility§

This trait is dyn compatible.

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