Enum borsh::maybestd::sync::mpsc::TryRecvError

[−] Show declaration

pub enum TryRecvError {
    Empty,
    Disconnected,
}

[−] Expand description

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

[−] Expand description

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

Disconnected

[−] Expand description

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

pub fn description(&self) -> &str[−]

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn source(&self) -> Option<&(dyn Error + 'static)>[−]

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>[−]

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<RecvError> for TryRecvError[+]

pub fn from(err: RecvError) -> TryRecvError[−]

Converts a RecvError into a TryRecvError.

This conversion always returns TryRecvError::Disconnected.

No data is allocated on the heap.

impl PartialEq<TryRecvError> for TryRecvError[+]

[+] Show hidden undocumented items

pub fn eq(&self, other: &TryRecvError) -> bool[−]

This method tests for self and other values to be equal, and is used by ==.

[+] Expand attributes

#[must_use]pub fn ne(&self, other: &Rhs) -> bool[−]

This method tests for !=.
