Enum MintError 

pub enum MintError {
    DuplicateCatchAll(usize),
    ManifestTooLarge {
        size: usize,
        cap: usize,
    },
    Token(TokenError),
}

Why a mint was rejected.

Variants

DuplicateCatchAll(usize)

More than one catch-all variant — selection order would be ambiguous to authors even though declaration order breaks the tie.

ManifestTooLarge

The serialized manifest exceeds the size cap; move bodies to media.

Fields

size: usize

Serialized size observed.

cap: usize

The cap (MANIFEST_SIZE_CAP_BYTES).

Token(TokenError)

Token generation failed (entropy or length configuration).

Trait Implementations

impl Debug for MintError

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

Formats the value using the given formatter.

impl Display for MintError

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

Formats the value using the given formatter.

impl Error for MintError

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<TokenError> for MintError

fn from(source: TokenError) -> Self

Converts to this type from the input type.
