Enum TypeSizeHint

pub enum TypeSizeHint {
    Static(usize),
    RuntimeArray(ArraySizeHole),
    Matrix(MatrixStrideHole),
    UnknownArrayStride(UnknownStrideHole),
}

A size hint for a type. This could be a statically known size, or need to resolve a hole before getting a more accurate.

Size hints resolve array sizes involving specialization constants.

If an array stride is found, it will calculate a statically known size with the array stride.

Variants

Static(usize)

A statically known type size hint.

RuntimeArray(ArraySizeHole)

The size of a runtime array, which is missing an element count.

Matrix(MatrixStrideHole)

A matrix type.

UnknownArrayStride(UnknownStrideHole)

The array stride is missing or unknowable.

Implementations

impl TypeSizeHint

pub fn declared(&self) -> usize
