Struct rustc_metadata::rmeta::LazyArray
source · struct LazyArray<T> {
position: NonZero<usize>,
num_elems: usize,
_marker: PhantomData<fn() -> T>,
}
Expand description
A list of lazily-decoded values.
Unlike LazyValue<Vec<T>>
, the length is encoded next to the
position, not at the position, which means that the length
doesn’t need to be known before encoding all the elements.
If the length is 0, no position is encoded, but otherwise,
the encoding is that of LazyArray
, with the distinction that
the minimal distance the length of the sequence, i.e.
it’s assumed there’s no 0-byte element in the sequence.

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.
