Enum SackError 

pub enum SackError {
    Truncated,
    TooManyRanges,
    Malformed,
}

Available on crate feature std only.

Errors returned by Sack::from_wire.

Variants

Truncated

The buffer is shorter than the structure it declares.

TooManyRanges

range_count exceeds MAX_SACK_RANGES. Checked before any allocation so an adversarial count cannot trigger OOM.

Malformed

The encoding is structurally invalid: range_count == 0, gap == 0 (adjacent ranges), a gap/len pair would underflow the sequence space, or ranges are not strictly descending and non-adjacent.

Trait Implementations

impl Clone for SackError

fn clone(&self) -> SackError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SackError

impl Debug for SackError

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

Formats the value using the given formatter.

impl Display for SackError

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

Formats the value using the given formatter.

impl Eq for SackError

impl Error for SackError

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 SackError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
