Struct ParamErrorContext 

pub struct ParamErrorContext {
    pub param_type: ParamType,
    pub field_name: Option<String>,
    pub message: String,
    pub source_message: Option<String>,
    pub raw_value: Option<String>,
    pub expected_type: Option<String>,
}

Detailed context for parameter extraction errors

Fields

param_type: ParamType

Parameter type (Json, Query, Path, Form, Header, etc.)

field_name: Option<String>

Field name if identifiable

message: String

Error message

source_message: Option<String>

Original source error (not cloneable, so we store the message)

raw_value: Option<String>

Original value (for debugging, sensitive data should be excluded)

expected_type: Option<String>

Expected type name

Implementations

impl ParamErrorContext

pub fn new(param_type: ParamType, message: impl Into<String>) -> Self

pub fn format_error(&self) -> String

Format error as single line (for Display trait)

pub fn format_multiline(&self, include_raw_value: bool) -> String

Format error as multiple lines (for detailed logging)
