Enum MtmdError 

pub enum MtmdError {
    ContextCreateFailed,
    BitmapCreateFailed,
    InvalidPath(NulError),
    PathNotUtf8,
    TokenizeError(i32),
    EncodeError(i32),

}

All errors that can be returned by the mtmd module.

Variants

ContextCreateFailed

The context could not be created (e.g. bad mmproj file).

BitmapCreateFailed

The bitmap could not be created.

InvalidPath(NulError)

A path could not be converted to a valid C string (embedded NUL byte or non-UTF-8).

PathNotUtf8

A path was not representable as UTF-8.

TokenizeError(i32)

mtmd_tokenize returned an error code.

EncodeError(i32)

mtmd_encode_chunk returned a non-zero code.

ChunkSaveFailed(i32)

mtmd_input_chunk_save returned a non-zero code.

ChunkLoadFailed

mtmd_input_chunk_load returned null — the buffer was not a chunk this build can restore.

BatchAddFailed(i32)

A chunk could not be added to a batch.

BatchCreateFailed

mtmd_batch_init returned null.

EvalError(i32)

mtmd_helper_eval_chunks (or single-chunk variant) returned a non-zero code.

VideoInitFailed

A video stream could not be opened. Common causes: the build lacks video support (MTMD_VIDEO was OFF), ffmpeg/ffprobe is not on PATH, or the file is unreadable.

VideoReadError(i32)

mtmd_helper_video_read_next returned an error code (-2).

Trait Implementations

impl Debug for MtmdError

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

Formats the value using the given formatter.

impl Display for MtmdError

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

Formats the value using the given formatter.

impl Error for MtmdError

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<NulError> for MtmdError

fn from(source: NulError) -> Self

Converts to this type from the input type.
