Struct abi_stable::type_layout::CompTLField

pub struct CompTLField { /* private fields */ }

A TLField represented as a u64, expadable to a TLField by calling the expand method.

Implementations

impl CompTLField

pub const BIT_SIZE: u32 = 61u32

The amount of bits necessary to represent a CompTLField.

pub const fn new( name: StartLen, lifetime_indices: LifetimeRange, field_accessor: CompFieldAccessor, layout: TypeLayoutIndex, is_function: bool, ) -> Self

Constructs a CompTLField.

pub const fn name_start_len(&self) -> StartLen

Gets the range representing the name in the string slice field inside the SharedVars field of the TypeLayout that contains this.

pub const fn type_layout_index(&self) -> usize

Gets the index of the type layout of the field in the slice of type layouts inside the SharedVars field of the TypeLayout that contains this.

pub const fn is_function(&self) -> bool

Whether this field is a function. This is only true if the type is a function pointer(not inside some other type).

impl CompTLField

pub fn name(&self, strings: &'static str) -> &'static str

Gets the name of the field from SharedVars’s string slice.

pub fn lifetime_indices( &self, indices: &'static [LifetimeIndexPair], ) -> LifetimeArrayOrSlice<'static>

Gets the name of the field from SharedVars’s slice of lifetime indices.

pub fn field_accessor(&self, strings: &'static str) -> FieldAccessor

Gets the FieldAccessor for the type from SharedVars’s string slice, which describes whether a field is accessible,and how it is accessed..

pub const fn type_layout( &self, type_layouts: &'static [extern "C" fn() -> &'static TypeLayout], ) -> extern "C" fn() -> &'static TypeLayout

Gets the name of the field from SharedVars’s slice of type layouts.

pub fn expand( &self, field_index: usize, functions: Option<&'static TLFunctions>, vars: &'static SharedVars, ) -> TLField

Expands this CompTLField into a TLField.
