Struct rustc_metadata::rmeta::LazyTable
source · struct LazyTable<I, T> {
position: NonZeroUsize,
encoded_size: usize,
_marker: PhantomData<fn(_: I) -> T>,
}
Expand description
A list of lazily-decoded values, with the added capability of random access.
Random-access table (i.e. offering constant-time get
/set
), similar to
LazyArray<T>
, but without requiring encoding or decoding all the values
eagerly and in-order.
Fields
position: NonZeroUsize
encoded_size: usize
_marker: PhantomData<fn(_: I) -> T>

Layout
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
