pub fn invalid_format(message: impl Into<String>) -> FerrumError

Create an invalid format error (parsing/schema mismatch)

pub fn invalid_parameter(message: impl Into<String>) -> FerrumError

Create an invalid parameter error

pub fn io_str(message: impl Into<String>) -> FerrumError

Alias for io() - Create an I/O error from string

pub fn configuration(message: impl Into<String>) -> FerrumError

Alias for config() - Create a configuration error

pub fn deserialization(message: impl Into<String>) -> FerrumError

Alias for serialization() - Create a deserialization error

pub fn invalid_request(message: impl Into<String>) -> FerrumError

Alias for request_validation() - Create an invalid request error

pub fn is_retryable(&self) -> bool

Check if this is a retryable error

pub fn is_client_error(&self) -> bool

Check if this is a client error (4xx equivalent)

pub fn is_server_error(&self) -> bool

Check if this is a server error (5xx equivalent)

pub fn observability_failure_kind(&self) -> &'static str

Stable failure class used by product observability replay bundles.

This intentionally stays smaller than the full error enum because the replay validator has different evidence requirements for resource failures and generic panic/error failures.

pub fn observability_error_kind(&self) -> &'static str

Stable error-kind label for first-failure-event diagnostics.

Trait Implementations
