Enum MtpSessionError 

pub enum MtpSessionError {
    Init,
    Process,
    BadSeqId {
        seq_id: i32,
        n_seq: u32,
    },
    InvalidConfig(&'static str),
}

Errors raised by the MTP draft session.

Variants

Init

Returned when mtp_session_new fails (typically: model lacks MTP heads, or one of the contexts is incompatible).

Process

mtp_session_process returned false.

BadSeqId

Caller passed a sequence id outside [0, n_seq).

Fields

seq_id: i32

the offending seq id

n_seq: u32

configured number of sequences

InvalidConfig(&'static str)

Invalid session configuration (e.g. n_draft_max <= 0).

Trait Implementations

impl Debug for MtpSessionError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for MtpSessionError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

impl Error for MtpSessionError

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 provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.
