Struct Ref 

pub struct Ref<'a, T: ?Sized> { /* private fields */ }

Implementations

impl<'a> Ref<'a, [u8]>

pub unsafe fn project<U: ?Sized>(self, ptr: *const U) -> Ref<'a, U>

Project a byte borrow into another typed view over the same underlying bytes. The new guard owns the same release mechanics . when the returned Ref<U> drops, the underlying account borrow is released exactly as if the original byte borrow had dropped.

Safety

ptr must point inside the byte slice that this Ref<[u8]> guards (offset bounds checked by the caller), the pointee must be valid U for any bit pattern (U: Pod-style), and ptr must satisfy U’s alignment requirements. Hopper’s typed access APIs enforce this by requiring alignment-1 wire/pod types. The returned Ref<U> inherits the source guard’s lifetime, so the account stays read-borrowed for as long as the typed view lives.

pub fn slice_from(self, offset: usize) -> Ref<'a, [u8]>

Narrow a shared byte-slice borrow to a tail starting at offset.

pub fn slice( self, offset: usize, len: usize, ) -> Result<Ref<'a, [u8]>, ProgramError>

Narrow a shared byte-slice borrow to a checked sub-slice.
