Struct SegmentBorrow 

pub struct SegmentBorrow {
    pub key_fp: u64,
    pub key: Address,
    pub offset: u32,
    pub size: u32,
    pub kind: AccessKind,
}

A single active segment borrow.

Carries both a fast u64 fingerprint and the full 32-byte account address. The fingerprint is the hot-path comparator; the full address resolves collisions so conflict detection is never probabilistic.

Fields

key_fp: u64

Fast-path prefix of the account address.

key: Address

Full account address, authoritative identity, checked whenever the fast-path fingerprint matches. Pre-audit we relied on the fingerprint alone and claimed it was “collision-free for any realistic instruction”; that was probabilistic, not a guarantee.

offset: u32

Byte offset within the account data.

size: u32

Byte size of the borrowed segment.

kind: AccessKind

Access kind (read or write).
