Trait StreamResultExt

pub trait StreamResultExt<T, E1, E2>
where
    E1: Error,
    E2: Error,
{
    // Required methods
    fn map_source_err<E, F>(self, f: F) -> StreamResult<T, E, E2>
       where E: Error,
             F: FnOnce(E1) -> E;
    fn map_sink_err<E, F>(self, f: F) -> StreamResult<T, E1, E>
       where E: Error,

Additional methods for StreamResult

Required Methods

fn map_source_err<E, F>(self, f: F) -> StreamResult<T, E, E2>

where E: Error, F: FnOnce(E1) -> E,

Map the error if it is a SourceError

fn map_sink_err<E, F>(self, f: F) -> StreamResult<T, E1, E>

where E: Error, F: FnOnce(E2) -> E,

Map the error if it is a SinkError

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
