Enum StreamingError 

pub enum StreamingError {
    InvalidState {
        message: String,
    },
    IoError(Error),
    XmlError(Error),
    BuildError(BuildError),
}

Errors that can occur during streaming operations

Comprehensive error types for streaming DDEX XML generation, including state management errors, I/O issues, and XML formatting problems.

Example

use ddex_builder::streaming::{StreamingBuilder, StreamingError};

match streaming_builder.write_resource(/*...*/) {
    Ok(resource_ref) => println!("Resource written: {}", resource_ref),
    Err(StreamingError::InvalidState { message }) => {
        eprintln!("Invalid state: {}", message);
    }
    Err(StreamingError::IoError(io_err)) => {
        eprintln!("I/O error: {}", io_err);
    }
    Err(other_err) => eprintln!("Other error: {}", other_err),
}

Variants

InvalidState

Invalid state transition (e.g., writing resources after finishing message)

Fields

message: String

Description of the invalid state and what operation was attempted

IoError(Error)

I/O error during streaming operations (writing to output, flushing buffers)

XmlError(Error)

XML writing or formatting error

BuildError(BuildError)

General build error from the underlying builder system

Trait Implementations

impl Debug for StreamingError

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

Formats the value using the given formatter.

impl Display for StreamingError

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

Formats the value using the given formatter.

impl Error for StreamingError

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.
