Enum FieldAttribute

#[non_exhaustive]
#[repr(C)]
pub enum FieldAttribute {
    Sensitive,
    SkipSerializing,
    SkipSerializingIf(for<'mem> unsafe fn(PtrConst<'mem>) -> bool),
    Rename(&'static str),
    Default(Option<for<'mem> unsafe fn(PtrUninit<'mem>) -> PtrMut<'mem>>),
    Arbitrary(&'static str),
}

An attribute that can be set on a field

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Sensitive

Marks field as containing sensitive information

SkipSerializing

Skip serializing this field.

SkipSerializingIf(for<'mem> unsafe fn(PtrConst<'mem>) -> bool)

Skip serializing this field if the function identified by .0 evaluates to true.

Rename(&'static str)

Specifies an alternative name for the field (for serialization/deserialization)

Default(Option<for<'mem> unsafe fn(PtrUninit<'mem>) -> PtrMut<'mem>>)

Indicates the field has a default value (the value is which fn to call for default, or None for Default::default)

Arbitrary(&'static str)

Custom field attribute containing arbitrary text

Trait Implementations

impl Clone for FieldAttribute

fn clone(&self) -> FieldAttribute

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FieldAttribute

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

Formats the value using the given formatter.

impl Hash for FieldAttribute

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FieldAttribute

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