Struct DiagnosticView 

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

A borrowed controlled-diagnostics projection of one descriptor-validated context.

DiagnosticView exposes descriptor-approved diagnostic fields and key-only secret-presence markers for operational diagnostics. It never exposes source errors, caller locations, or backtraces and must not be serialized into public protocol responses. Like PublicErrorView, it borrows its inputs and performs no allocation after ErrorContext has been constructed.

Implementations

impl<'a> DiagnosticView<'a>

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

Validates context against descriptor and creates a controlled diagnostic view.

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 const fn condition(&self) -> CanonicalCondition

Returns the descriptor’s protocol-independent canonical condition.

pub const fn severity(&self) -> ErrorSeverity

Returns the descriptor’s operational severity.

pub const fn recovery_hint(&self) -> RecoveryHint

Returns the descriptor’s recovery advice.

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

Iterates present public, diagnostic, and redacted secret-presence fields.

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.
