Enum Error 

pub enum Error {
    ChecksumMismatch {
        algorithm: &'static str,
        url: String,
        expected: String,
        actual: String,
    },
    InvalidDownloadPath {
        path: PathBuf,
    },
    InvalidRangeResponse {
        url: String,
        details: String,
    },
    Io(Error),
    NotFound(String),
    Request(Error),
    SizeMismatch {
        url: String,
        expected: u64,
        actual: u64,
    },
    Source(Box<dyn Error + Send + Sync>),
    Status(StatusCode),
    Url(ParseError),
}

Errors produced by the transfer engine.

Source is the seam for caller-supplied failures: the URL resolver and the input item stream hand their own error types to the engine boxed through this variant, so the engine never needs to know about a consumer’s domain errors.

Implementations

impl Error

pub fn from_source(err: impl Into<Box<dyn Error + Send + Sync>>) -> Self

Wrap a caller-supplied error — from the URL resolver or the input item stream — as a Source. Shorthand for Error::Source(Box::new(err)); accepts anything boxable, including a &str/String message.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ParseError> for Error

fn from(source: ParseError) -> Self

Converts to this type from the input type.
