Struct rebound::info::Field

pub struct Field { /* fields omitted */ }

Info about a field on a Type, either named or unnamed. Allows getting a reference to or setting the content of this field on a Value, assuming the reflection was configured to allow it.

Implementations

impl Field

pub unsafe fn new_named(
    get_ptr: Option<Box<dyn Fn(&'a Value<'a>) -> Value<'a>>>,
    set_ptr: Option<Box<dyn Fn(&mut Value<'_>, Value<'static>)>>,
    name: &'static str,
    assoc_ty: Type,
    field_ty: Type
) -> Field

Internal Function, creates a new named field

Safety

Should only be called within a Reflected item's fields implementation

pub unsafe fn new_tuple(
    get_ptr: Option<Box<dyn Fn(&'a Value<'a>) -> Value<'a>>>,
    set_ptr: Option<Box<dyn Fn(&mut Value<'_>, Value<'static>)>>,
    idx: usize,
    assoc_ty: Type,
    field_ty: Type
) -> Field

Internal Function, creates a new unnamed field

Safety

f Should only be called within a Reflected item's fields implementation

pub unsafe fn new_enum_named(
    get_ptr: Option<Box<dyn Fn(&'a Value<'a>) -> Value<'a>>>,
    set_ptr: Option<Box<dyn Fn(&mut Value<'_>, Value<'static>)>>,
    name: &'static str,
    assoc_ty: Type,
    assoc_var: Variant,
    field_ty: Type
) -> Field

Internal Function, creates a new named field for a variant

Safety

Should only be called within a Reflected item's fields implementation

pub unsafe fn new_enum_tuple(
    get_ptr: Option<Box<dyn Fn(&'a Value<'a>) -> Value<'a>>>,
    set_ptr: Option<Box<dyn Fn(&mut Value<'_>, Value<'static>)>>,
    idx: usize,
    assoc_ty: Type,
    assoc_var: Variant,
    field_ty: Type
) -> Field

Internal Function, creates a new unnamed field for a variant

Safety

Should only be called within a Reflected item's fields implementation

pub fn assoc_ty(&self) -> Type

Get the Type this field is defined on

pub fn ty(&self) -> Type

Get the Type of the data in this field

pub fn kind(&self) -> &FieldKind

Get the kind of this field, which contains name or index information

pub fn get_ref<'a>(&self, this: &'a Value<'a>) -> Result<Value<'a>, Error>

Get a reference to the data contained within this Field on a Value, assuming the Value is of the correct type and the operation is supported.

pub fn set(
    &self,
    this: &mut Value<'_>,
    other: Value<'static>
) -> Result<(), Error>

Set the data contained within this Field on a Value, assuming the Values of both this and other are of the correct type and the operation is supported.

Trait Implementations

impl Debug for Field

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

Formats the value using the given formatter.
