Enum SeedError 

pub enum SeedError {
    WrongLength(usize),
    AllZero,
}

Why some bytes are not a usable identity seed.

Named variants rather than a string for the same reason super::hook::RunHookError has them: this material is secret, and a message that quoted what it rejected would put key material into a log line and a response body.

Variants

WrongLength(usize)

Not exactly SEED_BYTES bytes. Carries what was found, because a truncated payload and a padded one are different bugs on the composition side.

AllZero

Every byte is zero. A caller that produced it has a broken random source, and accepting it would install an identity every other broken caller shares.

Trait Implementations

impl Debug for SeedError

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

Formats the value using the given formatter.

impl Display for SeedError

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

Formats the value using the given formatter.

impl Eq for SeedError

impl Error for SeedError

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 SeedError

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

Equality operator ==.

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

Inequality operator !=.
