Struct rustc_metadata::rmeta::table::Table[−][src]

pub(super) struct Table<I: Idx, T> where
    Option<T>: FixedSizeEncoding,  {
    _marker: PhantomData<(fn(_: &I), T)>,
    _bytes: [u8],
}
Expand description

Random-access table (i.e. offering constant-time get/set), similar to Vec<Option<T>>, but without requiring encoding or decoding all the values eagerly and in-order. A total of (max_idx + 1) * <Option<T> as FixedSizeEncoding>::BYTE_LEN bytes are used for a table, where max_idx is the largest index passed to TableBuilder::set.

Fields

_marker: PhantomData<(fn(_: &I), T)>_bytes: [u8]
