FieldSpec

Struct FieldSpec 

Source
pub struct FieldSpec { /* private fields */ }
Expand description

One validated field in a state template.

A field specification is immutable after template loading. Its index is the position of the corresponding payload slot in every SystemState created from the same StateSpec.

Implementations§

Source§

impl FieldSpec

Source

pub fn index(&self) -> usize

Returns the zero-based payload-slot index assigned by template order.

Source

pub fn name(&self) -> &str

Returns the field name used by typed SystemState accessors.

Source

pub fn type_tag(&self) -> &str

Returns the stable codec type tag declared by the template.

The tag identifies serialized meaning across processes and versions. It must not be interpreted as std::any::type_name::<T>().
