Struct macro_input_core::StructLint

pub struct StructLint<'a> { /* fields omitted */ }

a lint for syn::ItemStruct or syn::DeriveInput

Example

use macro_input::{DefaultValue, FieldDef, FieldDefs, StructLint};

const BAR_FIELD: FieldDef = FieldDef::new("foo", "bar", false, DefaultValue::Bool(None));
const BAZ_FIELD: FieldDef = FieldDef::new("foo", "baz", false, DefaultValue::Str(None));
const FOO_FIELDS: &[&FieldDef] = &[&BAR_FIELD, &BAZ_FIELD];
const FOO_FIELD_DEFS: FieldDefs = FieldDefs::new(FOO_FIELDS);

const FOO_LINT: StructLint = StructLint::new(FieldDefs::empty(), &FOO_FIELD_DEFS);

Implementations

impl<'a> StructLint<'a>

pub const fn new(
    struct_defs: &'a FieldDefs<'a>,
    fields_defs: &'a FieldDefs<'a>
) -> Self

create a new struct lint

struct_defs lints attribute on the structs itself and fields_defs lints the fields of the struct
