Enum ServiceError 

pub enum ServiceError {
    InvalidTransition(&'static str),
    Dependency(&'static str),
    Implementation(&'static str),
}

Generic error type for service operations.

The fabric itself never allocates or performs I/O in order to create error values. Services are free to define richer error enums and convert them into this type if needed.

This type uses &'static str messages to remain allocation-free and no_std-friendly.

Variants

InvalidTransition(&'static str)

The requested transition was not compatible with the current state.

Dependency(&'static str)

A required dependency was not in a compatible state.

Implementation(&'static str)

An implementation-specific failure.

Trait Implementations

impl Clone for ServiceError

fn clone(&self) -> ServiceError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ServiceError

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

Formats the value using the given formatter.

impl PartialEq for ServiceError

fn eq(&self, other: &ServiceError) -> 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.
