Struct FieldNames 

pub struct FieldNames(/* private fields */);

An ordered list of field names in a struct.

Implementations

impl FieldNames

pub fn empty() -> Self

Returns an empty list of names.

pub fn len(&self) -> usize

Returns the number of elements.

pub fn is_empty(&self) -> bool

Returns true if the number of elements is 0.

pub fn iter(&self) -> impl ExactSizeIterator<Item = &FieldName>

Returns a borrowed iterator over the field names.

pub fn get(&self, index: usize) -> Option<&FieldName>

Returns a reference to a field name, or None if index is out of bounds.
