Struct arrow2::io::odbc::write::Writer

source · [−]

pub struct Writer<'a> { /* private fields */ }

Expand description

A writer of Chunks to an ODBC [api::Prepared] statement.

Implementation

This struct mixes CPU-bounded and IO-bounded tasks and is not ideal for an async context.

Implementations

source

impl<'a> Writer<'a>

source

pub fn try_new(prepared: Prepared<'a>, fields: Vec<Field>) -> Result<Self>

Creates a new Writer.

Errors

Errors iff any of the types from Field is not supported.

source

pub fn write<A: AsRef<dyn Array>>(&mut self, chunk: &Chunk<A>) -> Result<()>

Writes a chunk to the writer.

Errors

Errors iff the execution of the statement fails.
