Enum BntoError 

pub enum BntoError {
    InvalidInput(String),
    UnsupportedFormat(String),
    ProcessingFailed(String),
    Cancelled,
    FileTooLarge(u64),
    OutOfMemory(String),
}

All possible errors from Bnto WASM node operations.

Each variant represents a different category of failure. The #[error("...")] attribute defines the display message.

Variants

InvalidInput(String)

The input data is invalid (wrong type, missing required field, etc.). The string contains a human-readable explanation of what’s wrong.

UnsupportedFormat(String)

The file format isn’t supported by this node. For example, trying to compress a .bmp when we only support JPEG/PNG/WebP.

ProcessingFailed(String)

Something went wrong while processing the file. This is a catch-all for errors during the actual work (compression, CSV parsing, etc.). The string explains what happened.

Cancelled

The user cancelled the operation (or the Web Worker was terminated). Not a “real” error — the user chose to stop.

FileTooLarge(u64)

A file is too large for browser processing. Browser memory is limited (~2GB), so we check file sizes before trying to process them.

OutOfMemory(String)

The browser ran out of memory while processing. WASM has a limited memory heap. If we try to load a huge image, we might exhaust it.

Trait Implementations

impl Debug for BntoError

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

Formats the value using the given formatter.

impl Display for BntoError

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

Formats the value using the given formatter.

impl Error for BntoError

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.
