Struct dbcrossbarlib::SharedArguments

source ·

pub struct SharedArguments<S: ArgumentState> { /* private fields */ }

Expand description

Arguments used by both the data source and destination.

Implementations

source

impl<S: ArgumentState> SharedArguments<S>

source

pub fn max_streams(&self) -> usize

How many concurrent data streams should we attempt to process at once?

This is available even for unvalidated arguments because it’s used by our top-level code as well as some of the individual drivers.

source

impl SharedArguments<Unverified>

source

pub fn new(
    schema: Schema,
    temporary_storage: TemporaryStorage,
    max_streams: usize
) -> Self

Create a new SharedArguments structure.

source

pub fn verify(self, _features: Features) -> Result<SharedArguments<Verified>>

Verify that this structure only contains supported arguments. This uses the type state pattern to keep track of whether our arguments have been verified to be supported.

source

impl SharedArguments<Verified>

source

pub fn schema(&self) -> &Schema

Get the table scheme used for this transfer.

source

pub fn temporary_storage(&self) -> &TemporaryStorage

Get the temporary storage available for use by this transfer.
