Enum Attr 

#[repr(u8)]
pub enum Attr {
    From = 0,
    Source = 1,
}

Error attribute types for field configuration.

Variants

From = 0

Marks a field as the error source and generates a From impl.

Usage: #[facet(error::from)]

This attribute:

• Marks the field as the source in Error::source()
• Generates a From<FieldType> for ErrorType implementation

Source = 1

Marks a field as the error source without generating a From impl.

Usage: #[facet(error::source)]

This attribute only marks the field as the source in Error::source().

Trait Implementations

impl Clone for Attr

fn clone(&self) -> Attr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Attr

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

Formats the value using the given formatter.

impl<'ʄ> Facet<'ʄ> for Attr

const SHAPE: &'static Shape

The shape of this type, including: whether it’s a Struct, an Enum, something else?

impl PartialEq for Attr

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