Enum TransferError 

#[non_exhaustive]
pub enum TransferError {
    InvalidContract,
    UnsupportedVersion,
    Limit,
    UnsafePath,
    Busy,
    Integrity,
    Storage,
    SourcesExhausted,
    Cancelled,
    Deadline,
    Source,
}

Controlled transfer failure.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidContract

Policy or descriptor is malformed.

UnsupportedVersion

Unknown serialized format version.

Limit

A resource budget would be exceeded.

UnsafePath

Untrusted path, symlink or filesystem permissions.

Busy

Another process/session holds the store lock.

Integrity

Persistent data or received block failed integrity validation.

Storage

Filesystem operation failed; resumable progress may already be durable.

SourcesExhausted

No authorized, usable source remains or bounded retries were exhausted.

Cancelled

Cooperative cancellation requested.

Deadline

Monotonic deadline expired.

Source

Selected provider failed or panicked.

Trait Implementations

impl Clone for TransferError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for TransferError

impl Debug for TransferError

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

Formats the value using the given formatter.

impl Display for TransferError

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

Formats the value using the given formatter.

impl Eq for TransferError

impl Error for TransferError

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.

impl PartialEq for TransferError

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

Equality operator ==.

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

Inequality operator !=.
