Struct SourceSlice 

pub struct SourceSlice { /* private fields */ }

A validated zero-copy view of owner’s bytes over [start, start + len).

The fields are private and SourceSlice::new is the only constructor, because the range is not a hint: a view whose end runs past the owner, or whose ends fall inside a multi-byte scalar, is not a Text. Neither is constructible, so bad ranges cannot surface far from their cause as an out-of-range slice or as a Text that reads empty.

#[repr(C)] fixes the field order, so the payload layout is stable.

Implementations

impl SourceSlice

pub unsafe fn new(owner: GcRef, start: usize, len: usize) -> Option<SourceSlice>

A view of owner’s bytes over [start, start + len), or None if that is not a Text: a range past the end, a length that overflows, or ends that are not UTF-8 scalar boundaries.

Safety

owner must be a live Text GcRef — its payload is read to validate the range.

pub fn owner(self) -> GcRef

The Text this view borrows from. Traced, so the backing stays alive.
