Struct YtError 

pub struct YtError {
    pub code: i32,
    pub message: String,
    pub attributes: Vec<(String, Vec<u8>)>,
    pub inner_errors: Vec<YtError>,
}

An error reported by the server, with its nesting preserved.

Fields

code: i32

message: String

attributes: Vec<(String, Vec<u8>)>

Attribute values are YSON, exactly as the wire carries them; they are kept as bytes so nothing is lost to a decoder this crate does not need.

inner_errors: Vec<YtError>

Implementations

impl YtError

pub fn from_proto(proto: &TError) -> Self

Reads the protobuf form, keeping the whole tree.

pub fn find(&self, code: i32) -> Option<&YtError>

The first error in the tree with this code, outermost first.

The useful question is almost never “what is the outer code” but “is this failure a NoSuchTransaction anywhere inside”, because retry and reporting decisions hang on the inner code.

pub fn has_code(&self, code: i32) -> bool

Whether this error or any error nested inside it has this code.

pub fn innermost(&self) -> &YtError

The innermost error along the first chain of inner errors — usually the one that names the real cause.

pub fn attribute(&self, key: &str) -> Option<&[u8]>

The value of an attribute, as raw YSON bytes.

Trait Implementations

impl Clone for YtError

fn clone(&self) -> YtError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for YtError

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

Formats the value using the given formatter.

impl Eq for YtError

impl Error for YtError

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.

impl PartialEq for YtError

fn eq(&self, other: &YtError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
