Struct ProblemDetails 

pub struct ProblemDetails {
    pub problem_type: String,
    pub title: String,
    pub status: u16,
    pub code: String,
    pub detail: Option<String>,
    pub instance: Option<String>,
}

RFC 9457 problem details payload used for server error responses.

The field names intentionally match the wire format so the same type can be reused by future client-side parsing without another translation layer.

Fields

problem_type: String

URI identifying the problem type.

title: String

Short, human-readable summary of the problem type.

status: u16

HTTP status code. Must match the response status line.

code: String

Machine-readable error code.

detail: Option<String>

Per-instance explanation of the error.

instance: Option<String>

Request path or URI for the failing resource.

Implementations

impl ProblemDetails

pub fn new( problem_type: &'static str, title: &'static str, status: StatusCode, code: &'static str, ) -> Self

Create a new problem details payload with the required RFC 9457 fields.

pub fn with_detail(self, detail: impl Into<String>) -> Self

Attach a problem-specific detail string.

pub fn with_instance(self, instance: impl Into<String>) -> Self

Attach the request instance path/URI.

Trait Implementations

impl Clone for ProblemDetails

fn clone(&self) -> ProblemDetails

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProblemDetails

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProblemDetails

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&ProblemDetails> for ProblemTelemetry

fn from(problem: &ProblemDetails) -> Self

Converts to this type from the input type.

impl PartialEq for ProblemDetails

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ProblemDetails

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
