Struct ErrorContext 

pub struct ErrorContext { /* private fields */ }

Redaction-aware structured context for errors.

Context retains at most 16 unique catalog fields. The first value for a name wins and insertion order is preserved. Duplicate and over-capacity inserts are ignored and recorded by Self::is_truncated.

Implementations

impl ErrorContext

pub const fn new() -> Self

Creates an empty context.

pub fn with_text(self, key: FieldKey<TextField>, value: impl AsRef<str>) -> Self

Adds bounded text under a catalog-owned text key.

Every Unicode control character is replaced with one space before the value is truncated at a UTF-8 boundary to the schema’s byte limit.

pub fn with_i64(self, key: FieldKey<I64Field>, value: i64) -> Self

Adds a signed integer under a catalog-owned key.

pub fn with_u64(self, key: FieldKey<U64Field>, value: u64) -> Self

Adds an unsigned integer under a catalog-owned key.

pub fn with_bool(self, key: FieldKey<BoolField>, value: bool) -> Self

Adds a Boolean under a catalog-owned key.

pub fn with_secret_presence(self, key: FieldKey<SecretPresenceField>) -> Self

Records the presence of secret-bearing input without accepting a value.

pub fn public_fields(&self) -> impl Iterator<Item = &ErrorContextField>

Iterates fields approved for public projections in insertion order.

pub fn is_empty(&self) -> bool

Returns whether the context contains no fields.

pub fn len(&self) -> usize

Returns the number of retained fields.

pub const fn is_truncated(&self) -> bool

Returns whether text, a duplicate field, or an over-capacity insert was truncated.
