Enum IoError 

#[repr(u8)]
pub enum IoError {
    NotGranted = 0,
    NoTask = 1,
    NoOutput = 2,
    OutOfRange = 3,
}

Why a read produced nothing.

Variants

NotGranted = 0

This hook’s entry does not declare capabilities.task_io.read: true. A value to branch on, never a trap: the session continues.

NoTask = 1

No task is in scope at this lifecycle event — see the timing table.

NoOutput = 2

A task is in scope but its agent loop has not produced result text. Either the loop has not reached a terminal arm yet, or it ended on a path that returned an error without producing any.

OutOfRange = 3

offset is past the end of the value, or lands inside a multi-byte UTF-8 character.

Implementations

impl Eq for IoError

impl Error for IoError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
