Struct FieldVTable

#[non_exhaustive]
#[repr(C)]
pub struct FieldVTable {
    pub skip_serializing_if: Option<SkipSerializingIfFn>,
    pub default_fn: Option<DefaultInPlaceFn>,
}

Vtable for field-specific operations

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

skip_serializing_if: Option<SkipSerializingIfFn>

Function to determine if serialization should be skipped for this field

default_fn: Option<DefaultInPlaceFn>

Function to get the default value for this field

Implementations

impl FieldVTable

pub const fn builder() -> FieldVTableBuilder

Returns a builder for FieldVTable

Trait Implementations

impl Clone for FieldVTable

fn clone(&self) -> FieldVTable

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldVTable

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

Formats the value using the given formatter.

impl Hash for FieldVTable

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

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 FieldVTable

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