Enum BlockError 

pub enum BlockError<B> {
    BlockSizeMismatch {
        expected: usize,
        actual: usize,
        block: B,
    },
}

Error returned by block state transitions.

Every variant carries the originating block back to the caller so that the block is never silently leaked on failure. The caller can inspect the error, recover the block from the variant, and retry or drop it as needed.

Variants

BlockSizeMismatch

The number of tokens in the provided data did not match the block’s fixed size. The block is returned in the block field.

Fields

expected: usize

actual: usize

block: B

Trait Implementations

impl<B: Debug> Debug for BlockError<B>

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

Formats the value using the given formatter.

impl<B> Display for BlockError<B>

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

Formats the value using the given formatter.

impl<B> Error for BlockError<B>

where Self: Debug + Display,

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>)
