Comprehensive error types for Syna database operations.

Examples

use synadb::{SynaDB, SynaError, Result};

fn example() -> Result<()> {
    let mut db = SynaDB::new("test.db")?;
     
    // Empty keys are rejected
    match db.append("", 42i64.into()) {
        Err(SynaError::EmptyKey) => println!("Empty key rejected"),
        _ => {}
    }
     
    Ok(())
}

Variants

Io(Error)

I/O error during file operations.

Serialization(Error)

Serialization or deserialization error.

NotFound(String)

Database not found in the global registry.

InvalidPath(String)

Invalid file path.

KeyNotFound(String)

Key not found in the database.

CorruptedEntry(u64)

Corrupted entry detected at the given file offset.

DecompressionFailed

LZ4 decompression failed.

EmptyKey

Empty key is not allowed.

KeyTooLong(usize)

Key exceeds maximum length (65535 bytes).

InvalidDimensions(u16)

Invalid vector dimensions (must be 64-4096).

DimensionMismatch

Vector dimension mismatch.

Fields

expected: u16

Expected number of dimensions

got: u16

Actual number of dimensions provided

CorruptedIndex(String)

Corrupted HNSW index file.

ShapeMismatch

Shape mismatch in tensor operations.

Fields

data_size: usize

Actual data size in bytes

expected_size: usize

Expected data size in bytes

TypeConversion

Type conversion error in tensor operations.

Fields

from_type: &'static str

Source type name

to_type: &'static str

Target type name

ModelNotFound(String)

Model not found in the registry.

ChecksumMismatch

Checksum mismatch when loading a model.

Fields

expected: String

Expected checksum from metadata

got: String

Computed checksum from loaded data

RunNotFound(String)

Experiment run not found.

RunAlreadyEnded(String)

Experiment run has already ended.

GpuUnavailable(String)

GPU is unavailable or not supported.

GpuOutOfMemory(String)

GPU out of memory.

IndexError(String)

Index operation error (e.g., FAISS index creation/search failed).

Trait Implementations

impl Debug for SynaError

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

Formats the value using the given formatter.

impl Display for SynaError

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

Formats the value using the given formatter.

impl Error for SynaError

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<Box<ErrorKind>> for SynaError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for SynaError

fn from(source: Error) -> Self

Converts to this type from the input type.
