source · pub(super) struct TableBuilder<I: Idx, T: FixedSizeEncoding> {
width: usize,
blocks: IndexVec<I, T::ByteArray>,
_marker: PhantomData<T>,
}
Expand description
Helper for constructing a table’s serialization (also see Table
).
Fields§
§width: usize
§blocks: IndexVec<I, T::ByteArray>
§_marker: PhantomData<T>
Implementations§
source§impl<I: Idx, const N: usize, T: FixedSizeEncoding<ByteArray = [u8; N]>> TableBuilder<I, T>
impl<I: Idx, const N: usize, T: FixedSizeEncoding<ByteArray = [u8; N]>> TableBuilder<I, T>
sourcepub(crate) fn set(&mut self, i: I, value: 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.

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.
