Error type for download operations.

Designed to be serializable across FFI boundaries (Tauri, CLI, etc.) without depending on non-serializable types like std::io::Error.

Variants

Io

I/O error during file operations.

Fields

kind: String

The kind of I/O error (e.g., “not found”, “permission denied”).

message: String

Detailed error message.

Network

Network/HTTP error during download.

Fields

message: String

Detailed error message.

status_code: Option<u16>

HTTP status code if available.

NotFound

Model or file not found on the remote server.

Fields

message: String

What was not found (model ID, file, etc.).

InvalidQuantization

Invalid quantization specified.

Fields

value: String

The invalid quantization string.

ResolutionFailed

Failed to resolve quantization to a file.

Fields

message: String

Detailed error message.

QueueFull

Queue is full, cannot add more downloads.

Fields

max_size: u32

Maximum queue capacity.

AlreadyQueued

Download is already queued.

Fields

id: String

The download ID that’s already in the queue.

NotInQueue

Download not found in queue.

Fields

id: String

The download ID that wasn’t found.

Cancelled

Download was cancelled by user.

Interrupted

Download was interrupted and can be resumed.

Fields

bytes_downloaded: u64

Bytes downloaded before interruption.

IntegrityFailed

Integrity check failed (checksum mismatch).

Fields

expected: String

Expected checksum.

actual: String

Actual checksum computed.

Other

General/uncategorized error.

Fields

message: String

Error message.

Implementations

impl DownloadError

pub fn io(kind: impl Into<String>, message: impl Into<String>) -> Self

Create an I/O error from kind and message strings.

pub fn from_io_error(err: &Error) -> Self

Create an I/O error from a std::io::Error.

This captures the error kind name and message for serialization.

pub fn network(message: impl Into<String>) -> Self

Create a network error.

pub fn network_with_status(message: impl Into<String>, status_code: u16) -> Self

Create a network error with HTTP status code.

pub fn not_found(message: impl Into<String>) -> Self

Create a not found error.

pub fn invalid_quantization(value: impl Into<String>) -> Self

Create an invalid quantization error.

pub fn resolution_failed(message: impl Into<String>) -> Self

Create a resolution failed error.

pub const fn queue_full(max_size: u32) -> Self

Create a queue full error.

pub fn already_queued(id: impl Into<String>) -> Self

Create an already queued error.

pub fn not_in_queue(id: impl Into<String>) -> Self

Create a not in queue error.

pub fn integrity_failed( expected: impl Into<String>, actual: impl Into<String>, ) -> Self

Create an integrity check failed error.

pub fn other(message: impl Into<String>) -> Self

Create a generic error.

pub const fn is_recoverable(&self) -> bool

Check if this error is recoverable (can retry).

pub const fn is_cancelled(&self) -> bool

Check if this is a cancellation.

pub fn user_message(&self) -> String

Convert to a user-friendly message.

Trait Implementations

impl Clone for DownloadError

fn clone(&self) -> DownloadError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DownloadError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DownloadError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DownloadError

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

Formats the value using the given formatter.

impl Error for DownloadError

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 DownloadError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for DownloadError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for DownloadError

impl StructuralPartialEq for DownloadError
