Enum HkdfError 

pub enum HkdfError {
    OutputTooLong {
        requested: usize,
        max: usize,
    },
}

Errors from HKDF expansion.

Variants

OutputTooLong

Requested output exceeds the RFC 5869 limit of 255 × HashLen. The previous implementation’s u8 block counter wrapped here, silently producing repeating (non-uniform) key material.

Fields

requested: usize

max: usize

Trait Implementations

impl Debug for HkdfError

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

Formats the value using the given formatter.

impl Display for HkdfError

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

Formats the value using the given formatter.

impl Error for HkdfError

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>)
