Struct VocabError 

pub struct VocabError {
    pub code: ErrorCode,
    pub token: Option<TokenId>,
    pub detail: &'static str,
}

A structured vocabulary-boundary error.

Fields

code: ErrorCode

Stable machine code (EmptyToken or MalformedTokenizer).

token: Option<TokenId>

The offending token id, when one applies.

detail: &'static str

Advisory detail. Not the machine contract.

Implementations

impl VocabError

pub fn empty_token() -> Self

An empty-byte token was rejected at the choke-point.

pub fn malformed_tokenizer(detail: &'static str) -> Self

Tokenizer metadata (not a byte payload) was malformed.

pub fn malformed_tokenizer_for(token: TokenId, detail: &'static str) -> Self

Tokenizer metadata was malformed because of a specific, known token id.

pub fn limit_exceeded(detail: &'static str) -> Self

A vocabulary resource cap was exceeded; the input is well-formed but too large.

Trait Implementations

impl Clone for VocabError

fn clone(&self) -> VocabError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VocabError

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

Formats the value using the given formatter.

impl Display for VocabError

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

Formats the value using the given formatter.

impl Eq for VocabError

impl Error for VocabError

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 VocabError

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

Equality operator ==.

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

Inequality operator !=.
