Types
structAnnotationInfo
struct AnnotationInfoDescriptor of a single annotation instance: its type name plus key/value arguments.
Fields
info: WritStaticmap_bits: i64Methods
fn get_int(self: &AnnotationInfo, key: &[u8]) -> i64Reads an integer argument of the annotation by key; returns 0 if absent or non-integer.
fn get_str(self: &AnnotationInfo, key: &[u8]) -> StringViewReads a string argument of the annotation by key; returns an empty view if absent.
fn type_name(self: &AnnotationInfo) -> StringViewReturns the fully-qualified annotation type name (e.g. "reflect_basic::Deprecated").
structAnnotationsView
struct AnnotationsViewArray view over a TypeInfo’s annotation instances, obtained via TypeInfo::annotations.
Fields
arr_bits: i64info: WritStaticMethods
fn get(self: &AnnotationsView, idx: u64) -> AnnotationInfoReturns the annotation descriptor at index idx.
fn len(self: &AnnotationsView) -> u64Returns the number of annotation instances.
structFieldInfo
struct FieldInfoDescriptor of a single struct field: its name and the name of its type.
Fields
info: WritStaticmap_bits: i64Methods
fn name(self: &FieldInfo) -> StringViewReturns the field’s name.
fn type_name(self: &FieldInfo) -> StringViewReturns the name of the field’s type (primitives as spelled, named types by bare name);
types the emitter cannot name read as "?".
structFieldsView
struct FieldsViewArray view over a TypeInfo’s field descriptors, obtained via TypeInfo::fields.
Fields
arr_bits: i64info: WritStaticMethods
fn get(self: &FieldsView, idx: u64) -> FieldInfoReturns the field descriptor at index idx.
fn len(self: &FieldsView) -> u64Returns the number of field descriptors.
structTypeInfo
struct TypeInfoTyped view over the static reflection blob emitted by reflect::<T>().
Fields
inner: WritStaticMethods
fn annotation_count(self: &TypeInfo) -> u64Returns the number of annotation instances, without constructing an AnnotationsView.
fn annotations(self: &TypeInfo) -> AnnotationsViewReturns a view over the annotation instances attached to the type.
fn field_count(self: &TypeInfo) -> u64Returns the number of fields, without constructing a FieldsView.
fn fields(self: &TypeInfo) -> FieldsViewReturns a view over the type’s field descriptors.
fn is_data_plain(self: &TypeInfo) -> boolReturns true for DataPlain types: no relative-pointer (zone-offset) fields,
directly or transitively.
fn is_datatype(self: &TypeInfo) -> boolReturns true if the reflected type is a datatype (zoned struct), i.e. kind() == 2.
fn kind(self: &TypeInfo) -> i64Returns the type-kind code: 1 = plain struct, 2 = datatype (zoned struct), 3 = trait.
fn name(self: &TypeInfo) -> StringViewReturns the type’s unqualified name; the declaring package is read via pkg.
fn pkg(self: &TypeInfo) -> StringViewReturns the name of the package the type is declared in.
fn type_code(self: &TypeInfo) -> u64Returns the compiler-assigned unique type code for this type.
Functions
fnmake
fn make() -> TypeInfoCreates the TypeInfo for type _T via reflect::<_T>().
