Enum CcsdsNdmError 

#[non_exhaustive]
pub enum CcsdsNdmError {
    Io(Error),
    Format(Box<FormatError>),
    Validation(Box<ValidationError>),
    Epoch(EpochError),
    UnsupportedMessage(String),
    UnexpectedEof {
        context: String,
    },
}

The top-level error type for the CCSDS NDM library.

This enum wraps all possible errors that can occur during NDM parsing, validation, serialization, and I/O.

Example: Handling Parse Errors

use ccsds_ndm::messages::opm::Opm;
use ccsds_ndm::error::CcsdsNdmError;
use ccsds_ndm::kvn::parser::ParseKvn;

match Opm::from_kvn_str("CCSDS_OPM_VERS = 3.0\n...") {
    Ok(opm) => println!("Parsed: {:?}", opm),
    Err(e) => {
        if let Some(enum_err) = e.as_enum_error() {
            eprintln!("Invalid enum value '{}' for field '{}'", enum_err.value, enum_err.field);
        } else if let Some(validation_err) = e.as_validation_error() {
            eprintln!("Validation error: {}", validation_err);
        } else {
            eprintln!("Error: {}", e);
        }
    }
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Io(Error)

Errors occurring during I/O operations.

Format(Box<FormatError>)

Errors related to NDM format or syntax.

Validation(Box<ValidationError>)

Errors related to NDM data validation.

Epoch(EpochError)

Errors related to CCSDS Epochs.

UnsupportedMessage(String)

Error for unsupported CCSDS message types.

UnexpectedEof

Error when an unexpected end of input is reached.

Fields

context: String
