Enum SamplerInitError 

pub enum SamplerInitError {
    InteriorNul {
        field: &'static str,
        source: NulError,
    },
    NullReturn(&'static str),
    TooManyDrySequenceBreakers {
        distinct: usize,
        max: usize,
    },
}

Why a sampler could not be constructed.

The panicking constructors — LlamaSampler::grammar and friends — are kept for the common case where the grammar is a literal or came from ChatParams::grammar, and a failure really is a bug. These exist for the case they handle badly: a grammar, rule name or trigger pattern that arrived from a request, where an interior NUL is bad input rather than a broken invariant.

Variants

InteriorNul

A caller-supplied string contained an interior NUL, so it cannot cross the FFI boundary. field names which argument.

Fields

field: &'static str

Name of the offending argument.

source: NulError

The underlying conversion error.

NullReturn(&'static str)

llama.cpp returned null. For a grammar sampler this is what an unparseable GBNF grammar looks like; it logs the parse error itself.

TooManyDrySequenceBreakers

More distinct DRY sequence breakers than llama.cpp will accept. It silently drops the surplus, so this is reported rather than passed on.

Fields

distinct: usize

How many distinct breakers the caller supplied, counted the way llama.cpp counts them.

max: usize

The upstream limit, DRY_MAX_SEQ_BREAKERS.

Trait Implementations

impl Debug for SamplerInitError

impl Eq for SamplerInitError

impl Error for SamplerInitError

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 SamplerInitError

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

Equality operator ==.
