polars_utils::async_utils::error_capture

Struct ErrorHandle

pub struct ErrorHandle<ErrorT> { /* private fields */ }

Available on crate feature async-utils only.

Expand description

Handle to await the completion of multiple tasks. Propagates error results and resumes unwinds when joined.

Implementations§

Source §

impl<ErrorT> ErrorHandle<ErrorT>

Source

pub fn has_errored(&self) -> bool

Source

pub async fn join(self) -> Result<(), ErrorT>

Block until either an error is received, or all ErrorCaptures associated with this handle are dropped (i.e. successful completion of all wrapped futures).

§Panics

If a panic is received, this will resume unwinding.
