Struct PublicErrorView 

pub struct PublicErrorView<'a> { /* private fields */ }

A borrowed public projection of one descriptor-validated error context.

This view exposes only the descriptor’s stable identity, fixed public message, and descriptor-owned protocol projections. Descriptors with Exposure::Public may additionally expose declared public context fields; Exposure::Generic descriptors expose no dynamic fields. The view borrows its inputs and performs no allocation after the ErrorContext has been constructed.

use rocketmq_error::{ErrorContext, PublicErrorView, ROUTE_TOPIC_NOT_FOUND};

let context = ErrorContext::new();
let view = PublicErrorView::try_new(&ROUTE_TOPIC_NOT_FOUND, &context).unwrap();
let _ = view.context;

Implementations

impl PublicErrorView<'static>

pub const fn descriptor_only(descriptor: &'static ErrorDescriptor) -> Self

Creates a public view containing descriptor-owned data only.

This is the safe fallback when retained context fails descriptor validation. It preserves the original descriptor and performs no allocation.

impl<'a> PublicErrorView<'a>

pub fn try_new( descriptor: &'static ErrorDescriptor, context: &'a ErrorContext, ) -> Result<Self, ViewContextViolation>

Validates context against descriptor and creates a public safe view.

Every retained context field must exactly match a schema declared by descriptor. Missing fields are valid because descriptor schemas do not currently define required values.

Errors

Returns ViewContextViolation for the first retained context field that is undeclared or has a different complete schema.

pub const fn code(&self) -> ErrorCode

Returns the stable catalog code.

pub const fn message(&self) -> &'static str

Returns the descriptor’s fixed public message.

pub fn fields(&self) -> PublicFields<'a>

Iterates permitted public fields in descriptor declaration order.

Generic-exposure descriptors always return an empty iterator.

pub const fn projection(&self) -> ProjectionSpec

Returns descriptor-owned boundary projections.

pub const fn is_truncated(&self) -> bool

Returns whether context construction normalized, discarded, or truncated a value.

Trait Implementations

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

Formats the value using the given formatter.
