Struct rustc_metadata::rmeta::table::TableBuilder

pub(super) struct TableBuilder<I: Idx, T: FixedSizeEncoding> {
    width: usize,
    blocks: IndexVec<I, T::ByteArray>,
    _marker: PhantomData<T>,
}

Helper for constructing a table’s serialization (also see Table).

Fields

width: usize

blocks: IndexVec<I, T::ByteArray>

_marker: PhantomData<T>

Implementations

impl<I: Idx, const N: usize, T> TableBuilder<I, Option<T>>

where Option<T>: FixedSizeEncoding<ByteArray = [u8; N]>,

pub(crate) fn set_some(&mut self, i: I, value: T)

impl<I: Idx, const N: usize, T: FixedSizeEncoding<ByteArray = [u8; N]>> TableBuilder<I, T>

pub(crate) fn set(&mut self, i: I, value: T)

Sets the table value if it is not default. ATTENTION: For optimization default values are simply ignored by this function, because right now metadata tables never need to reset non-default values to default. If such need arises in the future then a new method (e.g. clear or reset) will need to be introduced for doing that explicitly.

pub(crate) fn encode(&self, buf: &mut FileEncoder) -> LazyTable<I, T>

Trait Implementations

impl<I: Idx, T: FixedSizeEncoding> Default for TableBuilder<I, T>

fn default() -> Self

Returns the “default value” for a type.

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.
