Struct HttpErrorMapping 

pub struct HttpErrorMapping {
    pub codes: BTreeMap<String, u16>,
    pub kinds: BTreeMap<String, u16>,
}

Route-level business error to HTTP status mapping.

codes maps an exact business error code to a status; kinds maps an exact business error kind to a status. Both tables are case-sensitive and may be empty.

The mapping is a separate route-level field and never lives on crate::error_handler::ErrorHandlerConfig. It carries no message or data: the reply body for a business error is exactly {"error": <code>, "kind": <kind>}, because runtime exchange data is untrusted and no mapping authorizes its disclosure.

Fields

codes: BTreeMap<String, u16>

Exact business error code to HTTP status.

kinds: BTreeMap<String, u16>

Exact business error kind to HTTP status.

Implementations

impl HttpErrorMapping

pub fn new() -> Self

Create an empty mapping (built-in defaults only).

pub fn with_code(self, code: impl Into<String>, status: u16) -> Self

Add a code entry, returning self for builder-style construction.

pub fn with_kind(self, kind: impl Into<String>, status: u16) -> Self

Add a kind entry, returning self for builder-style construction.

pub fn is_empty(&self) -> bool

Returns true when both tables are empty.

pub fn validate(&self) -> Result<(), HttpErrorMappingError>

Validate every entry: non-blank keys and statuses in 400..=599.

Errors

Returns the first HttpErrorMappingError found, checking the codes table before the kinds table.

pub fn explicit_status(&self, code: &str, kind: &str) -> Option<u16>

Explicit status for a business error, or None when no explicit entry applies.

The code table wins over the kind table. An out-of-domain entry is treated as absent, so resolution continues with the remaining precedence rules.
