Struct InputField

pub struct InputField {
    pub ident: Ident,
    pub attr_name: Option<String>,
    pub ty: Type,
    pub default: Option<DefaultExpression>,
    pub with: Option<Path>,

}

Fields

ident: Ident

attr_name: Option<String>

ty: Type

default: Option<DefaultExpression>

with: Option<Path>

skip: Option<SpannedValue<bool>>

If true, generated code will not look for this field in the input meta item, instead always falling back to either InputField::default or Default::default.

post_transform: Option<PostfixTransform>

multiple: Option<bool>

flatten: Flag

Implementations

impl InputField

pub fn as_codegen_field(&self) -> Field<'_>

Generate a view into this field that can be used for code generation.

fn as_codegen_default(&self) -> Option<DefaultExpression<'_>>

Generate a codegen::DefaultExpression for this field. This requires the field name in the Inherit case.

fn new(ident: Ident, ty: Type) -> Self

pub fn from_field(f: &Field, parent: Option<&Core>) -> Result<Self>

fn with_inherited(self, parent: &Core) -> Self

Apply inherited settings from the container. This is done after parsing to ensure deference to explicit field-level settings.

Trait Implementations

impl Clone for InputField

fn clone(&self) -> InputField

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InputField

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

Formats the value using the given formatter.

impl ParseAttribute for InputField

fn parse_nested(&mut self, mi: &Meta) -> Result<()>

Read a meta-item, and apply its values to the current instance.

fn parse_attributes(self, attrs: &[Attribute]) -> Result<Self>
