Expand description
A container for compile-time named struct info.
Implementations§
source§impl StructInfo
impl StructInfo
sourcepub fn new<T: Reflect + TypePath>(fields: &[NamedField]) -> Self
pub fn new<T: Reflect + TypePath>(fields: &[NamedField]) -> Self
sourcepub fn with_custom_attributes(self, custom_attributes: CustomAttributes) -> Self
pub fn with_custom_attributes(self, custom_attributes: CustomAttributes) -> Self
Sets the custom attributes for this struct.
sourcepub fn field_names(&self) -> &[&'static str]
pub fn field_names(&self) -> &[&'static str]
A slice containing the names of all fields in order.
sourcepub fn field(&self, name: &str) -> Option<&NamedField>
pub fn field(&self, name: &str) -> Option<&NamedField>
Get the field with the given name.
sourcepub fn field_at(&self, index: usize) -> Option<&NamedField>
pub fn field_at(&self, index: usize) -> Option<&NamedField>
Get the field at the given index.
sourcepub fn index_of(&self, name: &str) -> Option<usize>
pub fn index_of(&self, name: &str) -> Option<usize>
Get the index of the field with the given name.
sourcepub fn iter(&self) -> Iter<'_, NamedField>
pub fn iter(&self) -> Iter<'_, NamedField>
Iterate over the fields of this struct.
sourcepub fn type_path_table(&self) -> &TypePathTable
pub fn type_path_table(&self) -> &TypePathTable
A representation of the type path of the struct.
Provides dynamic access to all methods on TypePath
.
sourcepub fn type_path(&self) -> &'static str
pub fn type_path(&self) -> &'static str
The stable, full type path of the struct.
Use type_path_table
if you need access to the other methods on TypePath
.
sourcepub fn custom_attributes(&self) -> &CustomAttributes
pub fn custom_attributes(&self) -> &CustomAttributes
Returns the custom attributes for this item.
sourcepub fn get_attribute<T: Reflect>(&self) -> Option<&T>
pub fn get_attribute<T: Reflect>(&self) -> Option<&T>
Gets a custom attribute by type.
For dynamically accessing an attribute, see get_attribute_by_id
.
sourcepub fn get_attribute_by_id(&self, id: TypeId) -> Option<&dyn Reflect>
pub fn get_attribute_by_id(&self, id: TypeId) -> Option<&dyn Reflect>
Gets a custom attribute by its TypeId
.
This is the dynamic equivalent of get_attribute
.
sourcepub fn has_attribute<T: Reflect>(&self) -> bool
pub fn has_attribute<T: Reflect>(&self) -> bool
Returns true
if this item has a custom attribute of the specified type.
For dynamically checking if an attribute exists, see has_attribute_by_id
.
sourcepub fn has_attribute_by_id(&self, id: TypeId) -> bool
pub fn has_attribute_by_id(&self, id: TypeId) -> bool
Returns true
if this item has a custom attribute with the specified TypeId
.
This is the dynamic equivalent of has_attribute
