Enum ProfileError 

pub enum ProfileError {
    MissingField {
        field: Cow<'static, str>,
    },
    InvalidField {
        field: &'static str,
        value: String,
        reason: String,
    },
}

Errors that arise from a malformed or incomplete profile configuration.

These are distinct from message-validation errors (Error::Validation). A ProfileError signals that the profile itself is incorrect — e.g. a required field is missing from a profiles/**/*.json file. Message-level errors are represented by Error::Validation.

Variants

MissingField

A mandatory field is absent from the profile data.

This should never occur for profiles generated by cargo xtask codegen, but it can arise when building profiles programmatically.

Fields

field: Cow<'static, str>

The name of the missing field, e.g. "message_type" or "release".

Cow<'static, str> allows both static literals (zero-cost) and dynamically computed field names (owned String).

InvalidField

A field value is present but does not meet the profile’s constraints.

Fields

field: &'static str

The name of the invalid field.

value: String

The rejected value.

reason: String

Human-readable explanation.

Trait Implementations

impl Debug for ProfileError

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

Formats the value using the given formatter.

impl Display for ProfileError

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

Formats the value using the given formatter.

impl Error for ProfileError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<ProfileError> for Error

fn from(source: ProfileError) -> Self

Converts to this type from the input type.
