Struct PostcardError 

pub struct PostcardError {
    pub code: i32,
    pub pos: usize,
    pub message: String,
    pub source_bytes: Option<Vec<u8>>,
}

Postcard parsing error with optional source context for diagnostics.

Fields

code: i32

Error code from JIT

pos: usize

Position in input where error occurred

message: String

Human-readable message

source_bytes: Option<Vec<u8>>

Optional source bytes for diagnostics (hex dump context)

Implementations

impl PostcardError

pub fn with_source(self, bytes: &[u8]) -> Self

Attach source bytes for richer diagnostics.

impl PostcardError

pub fn from_code(code: i32, pos: usize) -> Self

Create an error from a JIT error code and position.

Trait Implementations

impl Clone for PostcardError

fn clone(&self) -> PostcardError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PostcardError

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

Formats the value using the given formatter.

impl Display for PostcardError

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

Formats the value using the given formatter.

impl Error for PostcardError

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.
