# Enum std::sync::mpsc::TryRecvError 1.0.0[−][src]

    pub enum TryRecvError {
        Empty,
        Disconnected,
    }

This enumeration is the list of the possible reasons that `try_recv` could not return data when called. This can occur with both a `channel` and a `sync_channel`.

## Variants

`Empty`

This channel is currently empty, but the Sender(s) have not yet disconnected, so data may yet become available.

`Disconnected`

The channel's sending half has become disconnected, and there will never be any more data received on it.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
