Enum LayoutCalculatorError

Source 
pub enum LayoutCalculatorError<F> {
    UnexpectedUnsized(F),
    SizeOverflow,
    EmptyUnion,
    ReprConflict,
}

Variants§

§

UnexpectedUnsized(F)

An unsized type was found in a location where a sized type was expected.

This is not always a compile error, for example if there is a [T]: Sized bound in a where clause.

Contains the field that was unexpectedly unsized.

§

SizeOverflow

A type was too large for the target platform.

§

EmptyUnion

A union had no fields.

§

ReprConflict

The fields or variants have irreconcilable reprs

Implementations§

Source§

impl<F> LayoutCalculatorError<F>

Source

pub fn without_payload(&self) -> LayoutCalculatorError<()>

Source

pub fn fallback_fmt(&self, f: &mut Formatter<'_>) -> Result

Format an untranslated diagnostic for this type

Intended for use by rust-analyzer, as neither it nor rustc_abi depend on fluent infra.
