Enum DataLinkError 

pub enum DataLinkError {
    IoError(Error),
    InvalidFrame,
    CrcError,
    AddressError(String),
    UnsupportedType,
}

Errors that can occur during data link layer operations.

This enum represents all possible error conditions that can arise when working with the data link layer, including I/O errors, protocol violations, and validation failures.

Examples

use bacnet_rs::datalink::{DataLinkError, Result};

fn validate_frame_size(size: usize) -> Result<()> {
    if size > 1500 {
        return Err(DataLinkError::InvalidFrame);
    }
    Ok(())
}

Variants

IoError(Error)

Network I/O error occurred.

This variant wraps standard I/O errors that occur during network operations, such as socket errors, timeouts, or connection failures.

InvalidFrame

Invalid frame format detected.

This error indicates that a received frame does not conform to the expected format for the data link type, such as invalid headers, incorrect frame structure, or protocol violations.

CrcError

CRC check failed during frame validation.

This error occurs when the calculated CRC/checksum does not match the expected value, indicating data corruption during transmission.

AddressError(String)

Address resolution or validation failed.

This error includes various address-related issues such as invalid address formats, unreachable destinations, or address conflicts. The string provides additional context about the specific issue.

UnsupportedType

Unsupported data link type for the requested operation.

This error occurs when attempting to use a data link type that is not supported by the current implementation or when mixing incompatible address types with data link types.

Trait Implementations

impl Debug for DataLinkError

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

Formats the value using the given formatter.

impl Display for DataLinkError

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

Formats the value using the given formatter.

impl Error for DataLinkError

Available on crate feature std only.

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.
