Struct TypedSegment 

pub struct TypedSegment<T: Pod, const OFFSET: u32> { /* private fields */ }

Compile-time typed segment descriptor: T is the overlay type, OFFSET is the absolute byte offset from the start of account data. Zero-sized.

// Matches Vault.balance at body offset 0, past the 16-byte header:
const VAULT_BALANCE: TypedSegment<WireU64, { HopperHeader::SIZE as u32 }>
    = TypedSegment::new();

let bal = account.segment_ref_typed(&mut borrows, VAULT_BALANCE)?;

Implementations

impl<T: Pod, const OFFSET: u32> TypedSegment<T, OFFSET>

pub const fn new() -> Self

Construct the marker. Runs entirely at compile time.

pub const fn offset() -> u32

The absolute byte offset of this segment (OFFSET const-generic).

pub const fn size() -> u32

The byte size of this segment (size_of::<T>(), folded at compile time).

pub const fn end() -> u64

One-past-the-end byte offset, widened like Segment::end.

pub const fn as_segment() -> Segment

Lower to a runtime Segment when a heterogeneous collection of segments is needed (e.g. a validation pass that iterates).

Trait Implementations

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

Formats the value using the given formatter.

impl<T: Default + Pod, const OFFSET: u32> Default for TypedSegment<T, OFFSET>

fn default() -> Self

Returns the “default value” for a type.
